My cat Is approximately 14 years old. over the past couple months she has been drinking excessive amounts of water. and when she urinates she seems to almost flood the cat box. I’m going through three times as much cat litter as I have in the past. I have her on Purina One urinary diet. but now she seems to be losing a lot of weight. and she has less energy. what can I do to solve this problem.
