Saddle Thrombus In Cats

The largest artery in the body that is the main “highway” for the propagation of oxygenated blood from thr heart to the tissues is the aorta. The feline aorta leaves the heart with oxygen rich blood and courses through the chest and ultimately through the abdomen heading toward the tail. At the level of the pelvis, the aorta splits into two smaller arteries that ultimately supply blood to the tissues of each leg. It is at this split where formed clots can get lodged, leading to a severe medical emergency called a saddle thrombus.

Saddle thrombus is exclusively a feline phenomena, causing a severe situation where the lodged clot cuts off blood supply to the legs. The lack of nutrient rich, oxygen rich blood reaching the tissues of the legs leads to severe pain, disuse of the legs and severe damage to the tissues, blood vessels, and nerves.

Saddle Thrombus

Typically, cats that are predisposed to saddle thrombus have underlying cardiac disease that increases turbulence to the flow of blood through the heart. This increased turbulence makes these patients more prone to the formation of clots. Cats with hyper-thyroidism are prone to a cardiac condition called hypertrophic cardiomyopathy. Therefore, saddle thrombus tends to be associated with cats that have hyperthyroidism.

Cats that have formed a saddle thrombus typically appear paralyzed, unable to move the rear legs. They are often vocalizing due to severe pain. When touched, the back legs are often cold and stiff, and sometimes there is panting and trouble breathing.

Due to the time sensitive nature of the irreversible consequences of saddle thrombus, as well as the severe pain that saddle thrombus causes, it is strongly recommended that one seek immediate veterinary care for one’s cat if saddle thrombus is suspected.

Saddle thrombus is diagnosed by a combination of history, presentation, cold/stiff rear legs, and lack of any palpable pulses in the rear legs. Chest x-rays will often indicate evidence of cardiac disease, and even congestive heart failure.

Prognosis is poor for saddle thrombus, even when found early. Treatment is geared toward managing pain and re-establishing blood supply to the legs through the use of IV clot busters such as heparin, or surgical removal of the clot. In many cases, however, the damage to the tissues, blood vessels, and nerves of the rear limbs is too severe and irreversible for treatment to offer a return quality of life, leaving euthanasia the most humane option for the patient.

    This week I had to make the horrible decision on what to do for one of my kitties. After being told that his heart was enlarged (not sure if that was from the beginning of his life or something that happened recently…I’m not a medical professional so I don’t know how that happens) and had a small amount fluid on his lungs along with the diagnosis of saddle thrombus we chose to humanely let him go. I could not imagine letting him live in pain since pets can not vocalize to us when something is wrong or risking him having another clot or some worse heart condition while we were at work and leaving him to suffer alone for hours. We were fortunate to be home when it happened this time and got him to the vet immediately. Sorry for the long story to get to the point of my post, but he is one from a litter that we fostered from kittens and decided to keep 3 of them. His sister passed away 3 years ago from some kind of unknown neurological issue. At least this is the only answer our vet could find. We now have only 1 of this litter left and he is 12 years old. It makes me very apprehensive that there is something in all the kittens from that litter (paranoid fur-mommy). Would a pre-emptive x-ray tell us anything that would help if the remaining kitty has a similar heart issue? Is there a medication he could take that might prevent a clot or is that even too dangerous to give them?

      Lillie, I am so sorry for your loss. :(

      you should contact Dr Eric Weisman for assistance. He has helped my kitty who suffered a blood clot on friday and the emergency vet wanted to put him down. But I refused at the time. I got 3 days of pain meds. In the mean time I got instruction from dr eric weisman about what suppliments to give my cat to break up the blood clot and keep it from leaking into his arteries as well as suppliments to support his healing. So far we are on day 4 and this cat went from not being able to move, to dragging his back legs, to scooting on his back feet. Here is the link to a youtube video i just posted today on how reamarkably WELL he is doing! contact me if you want further info on Dr Weisman.

        My Maine Coon Emma had 3 episodes this week of being fine, then drawing up the same left back leg as if arthritic, hissing, rolling on her back, and then 15 seconds later completely recovering. Vet xrayed her, said nothing found. We’re taking her to UC Davis specialist. Could you please tell me where is Dr Weisman? Thank you.

      • Veronica says:

        Hello, found out today my cat has this condition I was told by my vet to put her down but I couldn’t, went home with 5 days worth of pain meds,i would love to know what you did to help you cat please am desperate to save mine. Thanks

      • Veronica says:

        Hi found out my cat has the same condition was told by the vet that I had to put her down but I refused to give up on her so I went home with 5 days worth of pain medication, please let me know what you did to help your cat am desperate to save mine. Thanks

    • Bubba boy says:

      Hi thank you for your story. We are going through this at the moment. Our 18month old boy is in hospital as we speak. We make a decision about him tomorrow. So so sad

  2. Laurie says:

    This evening, I lost my beloved Odysseus to saddle thrombus. We made the decision to end his pain and it was so very hard to let him go. He was my very special cat friend and I will miss him dearly. He was 10 years old. This article is a spot on description of the symptoms and helps me to understand what happened to my little love. It also reassured me that we made the right decision. Thank you

    Saddle Thrombus is not necessarily only for cats. Ferrets will also be afflicted by this. It’s just as horrific for them. I just had one go through this two nights ago.

  4. Hannah mae says:

    I lost my dear tabby cat Joey to this this morning. At first I thought he had been hit by a car until I sadly found out the severity of it at the vets. I made the decision to put him down he was only 3 years old and I shall miss him dearly.this gives me understanding of what has happened and has been such an awful shock for us. Didn’t expect to loose him this soon it’s such a sad thing to happen and so rapidly. He seemed fine last night and then by morning couldn’t my little man ,x

  5. Lee says:

    Lost my lovely cat max on Sunday to saddle thrombus . I’d taken him to vets both previous days ( he was also on thyroid medication) because he’d been sick and breathing wasn’t quite right. He was given antisickness injection and steroid . He woke up Sunday I thought he was looking and feeling better when he was suddenly sick then howling and could not walk .Had to wait for an hour for vet to get to surgery . It was terrible . Nothing could be done so he was put to sleep . I can’t get over the shock miss him terribly . R I p max love you x

  6. Janice says:

    Just lost my little Belle (13) to saddle thrombus. Her brother, jasper(11), had it two years earlier. In both case I was woken up in the wee hours of the night by a screaming cat. The male was completely paralyzed in the hind end and Belle partially. Both had to be euthanized.

  7. Sue says:

    I lost my beloved 13 year old kitty, Sammy, to saddle thrombus on Saturday, October 10, 2015. He was the light of my life, a joyful purr kitty with a big personality. He had a heart murmur that we have been treating with medication since he was a kitten. He work us up at 7 a.m. on Friday howling in pain and we realized his back legs were paralyzed. We got him to the vet within 30 minutes. However, by Saturday morning he was in severe kidney failure and his temperature was dropping. We had to say goodbye to my sweet little buddy, the toughest day of my life. My husband and I are thankful that we were both home when it happened so that we could quickly get Sammy help. It’s a terrible thing…moments before he seemed perfectly fine.

  8. Lynda says:

    I lost my Mr. Pretty Boy from Saddle Thrombus on Friday morning. I had no idea that he was sick. It came so quickly.

  9. Lorrie says:

    I have tears in my eyes reading all the posts regarding saddle thrombus. I had never even heard of this condition until last night. My cat was eating, walking and breathing fine and in the blink of an eye, I heard this loud howling. I thought Jelly was locked in a closet and I checked all the closets and found him lying in a doorway on his side, gasping for breath and howling the loudest howl I ever heard. We immediately wrapped him in a blanket and took him to an ER vet. He was diagnosed with saddle thrombus and had to be euthanized. I can’t even put into words how heartbroken my husband and I are over Jelly’s demise. It would be different if we knew he was ill, but to be fine one minute and incapacitated the next is beyond my comprehension. Jelly was ten years old. We rescued from the woods when he was two years old and was the joy of our lives. RIP Jelly and all the other cats whom have been taken by this condition.

    • Kim says:

      Lorrie, I’m so sorry for your loss of Jelly! I lost my 11 1/2 year old cat, Rocky, early Saturday morning. Likewise, he seemed fine. He had come in to lie on the floor and started panting a few times. I knew this wasn’t normal, so I started talking to him. He stopped panting and seemed ok. He rolled over on his back and then back to his stomach. Suddenly, he tried to get up, but his rear legs were paralyzed. I was alarmed! Fearing a clot, I took him to an emergency vet clinic. I figured they’d put him on an IV and he’d be ok. I was so totally devastated by the Saddle Thrombus diagnosis! I had never heard of it. After some discussion, the vet said the most humane solution was euthanasia. While it killed me to have to do that, I knew it was the best thing to do. I too am stunned and so broken-hearted. He was a sweet boy, who’d been very clingy lately. Maybe he was trying to tell me something? Prayers for you and all of us who’ve lost a pet to this devastating condition. The emergency vet said there was nothing I could’ve done to prevent this, nor was there anything I did to cause it.

      • Lorrie says:


        I am so very sorry to hear about Rocky. It may be a coincidence, but Jelly, too was very clingy a couple weeks before this devastating condition caused his demise. I cannot stop hearing his howling in pain and reliving this horrific experience. I hope time will heal for all of us here.

      • Marilyn says:

        Oh my gosh! My cat is named Rocky (orange tabby) also. . We had to put him to sleep yesterday due to saddle thrombus! I am so heart broken! He was so cute yesterday-we gave him cat nip aka…”kitty cocaine”. . We went to breakfast and came home and he was fine. Then we came home from working out and he had crawled into a clean litter box and was crying in pain. We thought at first that we ran over him. We took him to the emergency clinic and they told us the news. I just went limp. My sweet bubbie. Me was so special to us. He loved to go on walks. He thought if the dog can—I can too! My neighbors would just laugh! He was the king of the culdasac. This is so sad. It happened so quickly. I hope you are doing okay. Thanks fur sharing– it helps to know other people feel the same way as a do for my furry friend

  10. Debra says:

    I lost my cat on 25th October to Saddle thrombus too. Scully was fine no health problems at all she still looked like a little kitten even though she was almost 18 years old she even had perfectly healthy teeth. She was with me constantly and it’s hard to accept that she was perfectly fine then I had to make the decision to put her to sleep but I know I couldn’t have watched her suffer. This is the most horrific thing to happen It’s just so sudden and unforgiving.

  11. Pete says:

    We lost our Tux man this past Thursday October 29,2015. I put him outside that morning before going to work and he seemed fine. When I got home that evening he was laying next to the house. When I went to check on him I noticed he had defacated on himself and had flies and maggots on him. I picked him up to clean him and noticed his rear legs were not working. We took him to the vet and they informed us he had saddle thrombus. After reading of this medical issue and where the animal is in severe pain my heart was broken realizing this most likely occurred early in the morning and he suffered all day and I wasn’t there for him. Tux was only four and he had just been treated for ear mites with steroids and was given his rabies shot two weeks prior. I thought he was under weight but the vet didn’t seem concerned about his weight. He will be truly missed.

    • craig says:

      To be 46 yr old male this is the hardest post ive ever made.I just had to put my Littleman down and didnt have no idea what had happen to him. After reading for days I was still a little confused because no one had posted about flies and egg’s on there cats rear end like mine had until now.But there;s no ? now with the back leg’s being paralyzed and all the same symptoms that ive read what my littleman had and I made the right call by putting him down , but the hard part is i work out of town and my neighbors found him and took him to vet and i wasnt even there to see him one more time and thats the part i’m having problems living with ,I loved that cat so much 12yrs with me threw everything others didnt want to be bothered with but he never complained one time
      Love you little buddy

  12. Sheila says:

    I just lost my 4 year old rescue cat Smokey this past weekend from this horrible condition. He woke me up in the middle of the night howling and unable to move his back legs. I took him to the animal ER immediately. After pain meds the X ray showed he had an enlarged heart and was in CHF. Because of the severity of his condition his long term prognosis was poor. I patted his head and talked to him while he was put to sleep. My heart is broken, but I feel I gave him a final act of love by letting him go before he suffered further.

  13. Lorrie says:

    Pete, I’m so sorry. You can’t feel guilty that you were away. This could have happened at any time. I was just fortunate that I was home when it happened but I still cannot get it out of my head. It will take a long time for us to heal.

  14. Kevin says:

    2 nights ago we lost our beloved Mozart to saddle thrombus. Mozart was my buddy for 15 years, and the loss is devastating. Mozart seemed his normal, happy self when we got home in the evening after work. He showed no signs of trouble or anything wrong. Shortly before bed, I was in my home office and Mozart walked down the hallway past the door. He seemed fine, and then he walked back and plopped down in the doorway, not a place he normally rests. Throughout his life, Mozart always had a way of telling me that something wasn’t right, and him laying there, and looking up at me was his sign. I started talking to him, asking if everything was okay, and when I walked over to him and he tried get up, and that’s when I noticed he had very limited use his hind legs. Mozart had a history of urinary tract problems, but this was something new. He started to make his way, dragging his feet, down the stairs, and I grabbed him. He then vomited more than I had ever seen him do before. My wife called the emergency animal hospital who said to bring him in immediately. At no point right before it happened, and during the ~25 minute car ride to the animal hospital did he ever scream out in pain. He was meowing and clearly distressed, but no loud cries. When we got to the hospital the vet told us the news that is was saddle thrombus and the prognosis was poor. Devastating. They put him on pain medication, and we were able to spend some time with him before they put him down. When he was on the table, he would try and stand up, but unlike only one hour before, he had no use of his back legs, and they were so cold, it was truly heart breaking. When they put him down, we both were there, and we held him, and talked to him, and we shared some final moments together. Mozart was always so loving, and loyal, and we were truly the lucky ones that he chose us to be his owners. It all happened so fast that it has been difficult to process. Like other people have mentioned on this forum, he seemed fine one minute and just over an hour later or so later we were saying our goodbyes. My heart goes out to all the loving cat owners on this forum whose beloved kitties were taken away from them because of saddle thrombus, hang in there.

    • Lorrie says:

      My heart goes out to you. My Jelly laid in the doorway as well, as he always did waiting for his Dad to come out of the shower. That is when he began a howling that I will never forget. This happened three weeks ago and although I can accept his passing, I can’t get the torture he was going through out of my head. It gets a little easier each day but never goes away. Think of all the good memories you had with Mozart and that you gave him the best home he could have ever had. That is what keeps me going.

  15. Cheryl delos Santos says:

    My Dante’ (3 years old) was fine this morning around 7am, Then around 9am my granddaughter said Dante’ couldn’t move his legs. He doesn’t meow like most cats do, but he was meowing just meowing not crying in pain it was like he was frustrated that he couldn’t move his hind legs. Took him to the Vet partly diagnosed with Saddle Thrombus. They took X-rays and blood work. The X-rays did not show any damage whatsoever. The blood work came back normal. They gave him two shots steroid and pain. Then Plavix and Baby Aspirin. It’s along shot but it’s worth trying. He’s not in pain. If he was I would have made the decision to put him to sleep. We will try this for 3 days

    • Hi Cheryl, I don’t know what happened to your cat. I appreciate your willingness to see if you could heal him. I nursed my cat through, and he’s still here with full mobility six months later.

  16. Britta Hardesty says:

    My 14 yr old cat is having similar, but not the same symptoms. She’s not in extreme pain as others described, but her hind legs aren’t working properly. It’s been degenerating over the last week. I took her to the vet initially because of blood in her stools and a week later she can only drag herself around. The vet thinks the two things are unrelated. Blood levels are normal, xrays are normal (well, some arthritis for my older, indoor, 6.5kg kitty). What do I do, can anyone provide any advice? The vet sent me home with her this weekend and I’ll go back on Monday and try an xray with iodine to look for subtle spinal issues that haven’t shown up yet. Any advice most appreciated. She’s in some pain if you help her move, she can void her bladder/bowels though sometimes with a bit of difficulty. She’s been on science diet metabolic or indoor or other limited food for a decade due to her weight. I don’t know what to do. thanks for any advice/feedback.

  17. Britta Hardesty says:

    Oh, and she does not have diabetes…

    • Lorrie says:

      I’m sorry you are going through this with your kitty. I do know that when my cat Peanut had acute renal disease, his back legs were very weak. However, you said the labs were negative. I would go to another vet for a second opinion. Please keep us posted!

  18. Minda says:

    We lost my husbands cat Ram who was 15 to this horrible condition in May. It was very similar circumstances to what everyone has described. The sudden collapse and howling and thrashing and rolling but no function in back legs. We rushed him to the emergency vet where he was quickly diagnosed and pts. Poor boy was so scared and in pain… Really no choice but to relieve their suffering. The main reason I came upon this post was because at the end of October my cat Dickens was pts after a couple months of unknown illness with nothing indicated in blood and urine tests but he developed sudden huge kidneys and renal failure. I have been searching and searching what could have happened to him. It is just a sick and horrible coincidence or was is related somehow even though they were completely different. Was it different manifestations of fip? I’m just lost. He was only 6 1/2 and I’m out of my mind with grief for both our boys. Bless you all in the sorrow of your losses.

  19. McKenzie says:

    My poor little Bailey (who was only 4) developed this condition on November 25th. I got home from working the overnight shift at work, to find him in his hiding space in the basement, making this horrible meow. I picked him and and he started to purr and it was then that I realized his back legs weren’t working.

    Bailey was rushed to the vet where he was diagnosed with saddle thrombus, and I was informed the only humane option was euthanasia. I found him at 9:00 am and by 10:30 he was gone. My boyfriend left for work at 7:00 am that morning, so that leaves two hours where he may have been suffering. I feel guilty that I wasn’t there, but am glad that at least he had the company of our other cat Birch. I miss and love him so much.

  20. Danielle says:

    I just lost my baby boy Frodo (5 years) this morning to Saddle. He lost complete mobility in both back legs. he seemed perfectly fine the day before. The Vet had diagnosed he and his brother with diabetes months before, and while they both were on medication, it only seemed like Sam was making progress. Frodo still could not put on weight. I wonder if he was misdiagnosed. Either way, this condition came out of nowhere, and I made the painful decision to put him down. He passed peacefully on my hand. RIP my little love. I will miss you pawing at my face in the morning <3

  21. Jenny says:

    My beloved Houdini…as I sit here in the vets office I researched the prognosis of this unknow and unfair disease. Why would this happen to us and why now? I don’t know…but I know I can’t take seeing you in pain. I’m so sorry kitty, I will forever love my Houdini, I guess this one is the last of your disappearing acts. See you soon baby

    • Sheila says:

      I am so sorry for you loss and everyone else’s loss who has posted here. I am still devastated over the sudden loss of my Smokey. I was with him when he was put to sleep as well. I will never forget it as long as live! He was only four years old! I will never forget him and the unconditional love he gave.

  22. Katie says:

    Wow, so many of us have recently gone through the same thing with our beloved kitties.

    It was October 7th (2015), and my 15-yr-old cat with hyperthyroidism had just taken a few bites of food, and then went out. He had not been venturing far or long recently, but I got busy with other things and then realized he was not right by the door. Long story short, a neighbor had found him collapsed on the grass. I hope he didn’t suffer for long before I got to him and was able to take him to the ER vet, where they told me, “it’s his heart…”

    I had to let my boy go, swaddled in my arms, and still “holding my hand” with his lovely paw.

    I feel really bad for those here who lost such young cats.

  23. Cary says:

    Steven was euthanized 3 hours ago with an aortic thromboembolism and a temperature of 96. He was 4.5 years old. I was told through the years that he had a heart murmur but thought his youth would prevail for now. At any rate, it makes me feel better to know that so many others have encountered this sad situation involving their beloved cats, and then made the choice to euthanize, so I add my story. Steven’s story. I am just sad. Also it hurts to think that he had been in pain and confusion all the while before I came near enough to hear him…he was in the barn where he was born and had lived happily, I think, with his brother and sister and mother. He may have been suffering for a night and most of a day. He was thrashing at times once I found him. He was crying. He was the biggest but most gentle and quiet of his family. The people at the Vet Office were so kind. They were sad along with me.

  24. Helen says:

    I lost my darling baby boy Peppercorn to a saddle thrombus 2 weeks ago and I’m only just starting to emotionally heal. He was the cutest, funniest, sweetest boy in the whole world, as far as I’m concerned. I’ve lost cats before but nothing has ever been this terrible. He was only 5 years old… For days afterwards I cried and lamented how unfair the world can be. We knew he had quite a serious heart murmur but I had never heard of this condition before. Pepper woke us up with his cries at 1:30 am, he was clearly in excruciating pain, trying to pull himself down the hall with his front legs and yowling. By 2:30am he was being euthanized in my arms at the emergency vet. He was in so much pain he actually bit both me and my wife, something he had never ever ever done before in his whole life, he was an incredibly gentle boy. My heart just breaks thinking of how much agony he was in. Absolutely terrible. I miss him every single day. Wherever you are, Pepper, I hope you are happy and carefree, playing with all the puffballs you could possibly want. I still love you.

  25. Hi, I want to provide a counter perspective to the doom and gloom about straddle thrombus. Especially in cats who are also hyperthyroid, as my cat was.

    It has been six months now since the harrowing night when my beloved cat Harvey suffered this condition.

    I was pressured by several veterinarians t euthanize him. I refused to do it.

    Using a combination of conventional medicine and energy healing, I had the clot on one side cleared within about 3 hours, and the clot for the other leg cleared in about two days.

    He was still limping about three months later so I applied more energy healing. He began what appeared to be a self-initiated physical therapy regimen of shaking his right leg vigorously on a regular basis. He no longer limps and is able to jump to the high cabinet again (50 inch vertical leap) as of a few days ago.

    I believe heart failure was preventable in our case. Unfortunately the very negative attitudes of the veterinarians we encountered those first couple weeks led to him not being properly treated.

    Heart disease is often reversible in hyperthyroid cats, and had he been treated immediately for hyperthyroidism … I believe he would not have ended up in heart failure.

    But … we did go through heart failure. It was awful, and we survived.

    Harvey was down to a scary 7 pounds and we had a number of scares after that with his respiratory rate. He had way more Lasix than he should have had … because it became very clear to me as the weeks went on … what slowed down his respiratory rate was not the Lasix but the thyroid meds … He needed a higher dosage.

    It has been a long journey, and probably we would not have survived it without the energy healing. I’ve seen miracles with my other cat as well, when we had a harrowing experience with severe kidney failure.

    Both my cats are here today because I said no to euthanasia. Harvey is up to 10.2 pounds, no longer requiring Lasix or appetite stimulants. Indeed, the only meds he is on now are nutritional supplements (which should probably be used in all of these cases), and sporadic thyroid meds and ranitidine to deal with the side effects of the thyroid meds.

    I truly believe that veterinarians could be achieving much better outcomes in straddle thrombus cases, if they were thinking more constructively. Of course, energy healing helps a lot.

    I thank God every day that Harvey is still here and happy, with full use of his back legs …

    Don’t give up. Learn some new skills. You can thank me later …

  26. p.s. I want to add that hyperthyroidism can be the cause of heart murmur, and so may be reversed with proper treatment of the hyperthyroidism.

    Beyond that though, in my extensive research, I learned that many people have seen reversal of heart murmurs with appropriate supplementation (e.g., CoQ10, L-carnitine, B vitamins, omega 3s, etc.) …

    If heart murmur is the usual cause of straddle thrombus, then vets ought to be more focused on healing heart murmurs. But if your vet is clueless, then by all means, do the research yourself as I did.

  27. Karen Kittell says:

    My story bears so many similarities with my 11 year old Persian, Mudge. The only difference being that it was his front leg that suddenly became paralyzed. He spent a little over 24 hrs. at the Emergency vet and was able to come home the next day with pain medication. 6 weeks later he curled up in his cat cave to nap after eating that morning and a little tummy rub later. A few hours later, not having seen him for awhile went to rouse him for a little play and he was just gone. I’d been sitting within feet of him all day and neither saw nor heard a thing. I just pray it was quick.

  28. Mandy says:

    As I write this my heart is in pieces because our 15 year old Abby was put under last night for this same thing. I had no clue. Perfect one minute. Chaos the next. Today I keep questioning if we did the right thing. Making this process harder on myself. After reading all these sad blogs I realize that we did make the right decision. My heart goes out to all who have had a pet loss. It is horrible. Especially when it is sudden. You will be terribly missed Abber Dabbers.

  29. vicki says:

    I just came from the emergency vet visiting my poor Porch kitty who was diagnosed with saddle thrombosis early yesterday. everyone says euthanize however there are a few success stories and she is not in pain at this time. they have her on pain meds and a drug to try to help dissolve the clot I recently had a dog bounce back from a life-threatening disease and she very well so I’m hoping that tomorrow when I take porch kitty to the vet they will give me some hope. she’s 15 years old I rescued her with a very bad thyroid condition which has been under control for the last year please pray everything works out

  30. Amy says:

    Our sweet Little Marshmellow we have had for 10 years passed away from Saddle Thormbus. Thursday 14th 2016. It has been really hard on the family because he was so special I never have heard about it before. So fast and quick death for a cat I pray for all who lost there loved cat to this disease.

    I too just had to put my beloved friend and companion of 17 and a 1/ 2 years down. She had a few issues over the years. A sub-total colectomy,14 years ago, hyperthyroidism for 4 years. 3 weeks ago she went out the front door, walked around to the back door and was walking funny. I thought she had a stroke. Rushed her to the vet. She did blood work,gave her a shot for pain and a corticosteroids. Within 12 hours she was doing great. Blood showed kidney disease. Put her on K/d food. Was doing great. A week later at 2:30 am she was howling in pain. Got her to the vet who diagnosed saddle thrombosis. Put her on heparin and cloprodogel (blood platelet thinner )Got the left side working but not the right. Tried for 10 days but the toes started to die, blood vessels collapsed, too old to amputate. Another vet said that massaging the limb for 15 min every few hours could help, but it was too late. This is a condition, I found out that occurs in cats, dogs, horses. Devastating. She loved me more than anyone else ever did. Rest in peace Krystal.

    We also lost our pet cat Rolex (yes Rolex)because of saddle thrombosis recently and we also miss him dearly. He was almost 19 years old and generally in good health. At the end, he was as others describe, unable to move his hind legs and crying in pain.
    I wanted to add some comments because, now that I understand more about the condition, I wonder if there were some warning signs that might have been treatable. Rolex was a large cat, at one point around 22 pounds. He was somewhat overweight but was a large cat. Over the last few years he had lost significant weight. Not surprising because of his age but he had particularly lost weight in his hindquarters. We also noticed that he seemed to be losing mobility in his hind legs. In the last 6 months or so, he had begun to hop up stairs instead of running.
    I now suspect that he may have had some partial blockage of the artery that was causing the leg muscles to weaken and waste away. If we had recognized the symptoms, we may have been able to treat the condition and prolong his life.

    My cat Baby was diagnosed tonight with Sadle Thrombosis. The vet wanted to put her down. I just couldn’t bear it tonight. She was given a pain injection and 2 doses to bring home. I am praYing for better results in the am. Can an u one that pulled their fur baby through please tell me what you did.
    What kinds of catfood was your cats eating? Maybe the cat food could be causing something to do this.
    Thanks in advance for any advice. I am devastated.

    • Hi, I’m Erika … I posted a few months ago about my cat Harvey so I wanted to encourage you. It’s now been nearly 10 months since our horrible night and Harvey is here on the bed with me, legs fully recovered. It hasn’t been an easy road but it’s been worth it. Is your cat tested for thyroid issues? If hyperthyroid … Getting thyroid under control is essential, must be done immediately to reverse heart disease. I have also been doing a ton of EFT tapping for my cat (I have free emergency protocol on my blog). I have been doing some supplements as well. Standard Process cardiac, kidney, CoQ10, B vitamins, and more. I found energy healing to be essential, not only for the long rehabilitation we experienced but also dealing with veterinary incompetence and having to figure out most of the answers myself.

      I know you’re devastated, it’s the most horrible experience of my life. Hang in there.

    We lost our 16 year old cat Nala today. She was crying/meowing in pain, dragging one of her legs. We tried to take her to the vet, but she passed away on the way there. I feel devastated.

  38. Lorrie says:

    I haven’t been here for about three months and I am saddened to see how many of your beloved cats have succumbed to this horrible condition called saddle thrombus. My Jelly passed away in October of last year and I still cry every single day. If he could have gone any other way, it would not be so difficult to overcome. I will never forget his saucer-like eyes and how scared he was on the way to the ER vet while he was howling in pain. I would like to tell you that the loss gets better in time, but for me it has not. RIP my Jelly Boy

    We lost our beloved Bubbles to this horrible disease February 25. We were aware of his heart condition early on and tried to make him as comfortable as possible using medications and not over exerting his heart. Bubbles actually had a few close calls with throwing smaller clots that would have symtoms lasting 10-15 minutes. The saddle thrombus came on very unexpected causing lower extremity paralysis with awful pain. Reading these posts has really helped me with coping with the horrible decision to let him go. My husband and I agreed on this decision because we felt even through further treatment he would eventually throw another clot. Thankfully we were home when this occurred so he didn’t have to suffer for hours while we were gone. Prayers to everyone effected by this painful condition.

    Tuesday, March 8th my cat Bombay was stricken with Saddle Thrombus. What amazed me was how quickly it hit. Two hours earlier he was in the basement with my wife, rolling around, getting petted, just a happy camper. Then boom. We put him to sleep that night. He was only 8, and we had rescued him from the Humane Society 31 months before. I hope you never have to experience this.

    My cat has been suffering with saddle thrombosis, his 16 years old near to 17. He suffered last January 23, 2016. He was half down paralyzed unable to move both his hind legs and tail. He was really in so much pain and could just utter a very soft sound. He was shocked and so depressed. Everything happen so quick in just a minute, he was still walking and jumping up the bed hours before seeing him on our bed turning and dragging himself on the bed, it was heart breaking to see him. I tried searching online about this illness I never heard off before. I thought I might lose him. I thank God, with lots of love and research online, my cat made it. He is now walking, he is in his recovery, please there is hope. Believe me there is hope!

    • Good for you! Yes, there is hope. Harvey is here on my bed, nearly 10 months after our horrible night. Legs fully recovered. If your cat is hyperthyroid, treating that immediately is essential. I have found supplements have also helped our recover – CoQ10, Standard Process cardiac and kidney, B vitamins, probiotics, etc. Hoping your cat also makes a full full recovery.

      you should contact Dr Eric Weisman for assistance. He has helped my kitty who suffered a blood clot on friday and the emergency vet wanted to put him down. But I refused at the time. I got 3 days of pain meds. In the mean time I got instruction from dr eric weisman about what suppliments to give my cat to break up the blood clot and keep it from leaking into his arteries as well as suppliments to support his healing. So far we are on day 4 and this cat went from not being able to move, to dragging his back legs, to scooting on his back feet. Here is the link to a youtube video i just posted today on how reamarkably WELL he is doing! contact me if you want further info on Dr Weisman.

    Lost our sweet Meow-Meow to this early this morning. Had never heard of this condition. Reading all the comments are so helpful and comforting to see that others have gone through this. The pain Meow-Meow was in will definitely haunt me for some time. Hugs to all of you who’ve gone through this.

  51. Surreal says:

    My cat was diagnosed this morning with Saddle Thrombus. However I’m confused as to what to do. The vet gave him some steroids and let us bring him home to see if he gets better. He is sleeping and doesn’t seem to be in pain. Does anyone know what the signs of progress/recovery are? And if you think I should put him down despite him not being in pain. He is paralyzed in his back legs and we’ve been massaging them and keeping them warm.

    I lost my 14 year old boy Toby to Saddlethrombus on Saturday, April 23. Shocking, so sudden. I feel horrible for anyone having to see their furry babies go through this. I’m praying his sister Kenzie does not succumb to the same illness. He had no know thyroid issues but history of heart disease most likely. I felt I had no choice but euthenasia once the vet told me about the condition and how much pain he was in. Being a Saturday and living out in the country this was the best decision for him. I could not see him suffering in pain for a couple days. The suddenness of this disease is horrible.

    Toby had vomited, laid in his vomit, complete paralysis in back legs. He was bellowing off and on. I could see it in his eyes how he didn’t understand what was happening to him.

    I had never heard of this condition, and I read here about the many cats that have had it. Reading about Saddle thrombus online is devastating.

    I can’t eat, sleep or focus. I’m still in shock, how can this happen. Toby was a cuddly loving boy, he aways was with me when I woke up. I hate goingto bed knowing he is not there.

      This just happened to my family at 11:30 last night. My son woke me up to tell me something was wrong with our cat Jacob. He said he cant walk and he pee’d on himself and threw up. Of course I run down stairs and it was the worst thing to see. He was breathing funny and was still incontinent. We rushed to the Vet ER and we got the news. Jacob was 17 yrs old. Although he was old he still was walking eating and doing his normal stuff. No indication at all. He was in pain and visibly scared. It was very hard to make the decision to let him go. But we couldn’t let him suffer the way he was. Its sad losing a pet this way because it happens without warning but I know he isn’t suffering and I am OK with it.
