I have been reading the posts from everyone and it seems there has been other cat parents who have experienced my nightmare. I took my cat in a week ago for antibiotics due to upper respiratory disease secondary to herpes. He is 10 years old and was eating, drinking and walking. The vet gave him depo medrol and he took a turn for the worse. He was in the hospital for 5 days and is now home. He has developed kidney failure, liver failure and diabetes. And they r claiming these were underlying issues. However no symptoms till the shot and I am devastated! We now are force feeding, and he is on 2 antibiotics, liver supplement, appetite stimulant, and insulin. Does anyone have a positive outcome to share and if so how long did this last? I feel they are to blame but they will never take responsibility. I just need.a little hope that we are doing all we can and he will pull through.
