This is just a thought but has the vet checked Fister's eye sight? I have to keep Grandma's water bowl in the exact same place or she can't find it. She can smell her food but I keep it in the same place too. Sometimes though, I still have to stick it right up to her nose before she knows it's there. The smellier the food the better she eats.

She was almost blind before I even knew there was a problem. Of course, she is an old girl now.
