Does anyone have any experience with this problem. My cat was just diagnosed with this after I found a rash on her belly. A biopsy was done and it came back positive for this. More tests need to be done to figure out what kind it is. All I'm hearing are horror stories from the vet which can lead to death. My cat is presently on medication and it's seeming to help but I'm told this is a problem that takes months to treat. Anyone have any experience with this? How did your cat do?
