Be sure to check between your cat’s paw pad webbing to make certain there are no thorns, grass spurs, or other foreign objects lodged there. Also, check for any split or damaged nails, as these are common injuries in cats. Lastly, check for any areas that may cause pain when gentle pressure is applied. Abscesses, or pockets of infection, are common in cats, especially those that spend significant periods of time outside. The cause of most abscesses in cats is bites from other animals, in most cases, other cats. Abscesses commonly at first present with limping, later progressing to swelling and oozing pus once the infection matures. As such, any visible swelling on an affected limb may be indicative of a mature abscess. If you come up empty checking all these things, then please refer to the following possible causes for your cat’s limping based on the history you provided.
Medially luxating patella
Cranial cruciate ligament rupture
