Princess is a 5 year old cat. In May I took her to the vet. She was under the weather. She was treated with an antibiotic and sent home. She did great for a month. On July 6, I had to take her back. She stopped eating 2 days prior. They admitted her for kidney failure. She has been in since. The first 2 days her BUM level and other levels improved. Day 3 no significant change. The vet said that they will change meds and see what happens. They claim there is still hope. Please help, is there hope, is she in pain, am I doing the right thing?
