Hi everyone, This poor guy is stuck in a foster house with 20 cats - and he's a people cat, NOT a cat's cat. He's been on Lantus and prednisone for at least a year, and doing very well. But he lives "alone" in an enclosed porch. I decided to foster him because I work at home and can pay attention to him. However, the food he's been eating (hills science diet z/d) is not being manufactured any more. He'll need to be transitioned to something else; the vet recommended Purina focus Rx. I'm starting to wonder if this is a good decision for me. I tend to assume the worst -- and that I'll be dealing with crazy BG levels on top of IBD flares and cleaning stuff off of carpets (I don't own this house!) It also really bothers me to feed a cat this type of crappy food and would be willing to make homemade. But Smokey is 15, his condition is well managed and do I really want to consider messing with that? I was told that once to make a change and find it doesn't work, that going back to status quo often doesn't work like it used to. Should I transition him to the Purina focus and just be done? should I then start at least reducing the Purina by adding homemade? I was told that once to make a change and find it doesn't work, that going back to status quo often doesn't work like it used to. We already know that reducing his prednisone messed with his blood sugar; the current foster and vet tried that just a few weeks ago. I guess I'm asking: at what point do you just do what the vet says?
