We tried the suggestions of variety of different raw food and he will eat them for a day then stop.he would starve himself before giving in. His behavior has also changed he won't play anymore and has become so cuddly its crazy and just over all calmer.except getting in fights with our other cat. He doesn't even want her near him anymore We took him to the vet and everything checked out and even put him on antibiotics as he was running a slight fever as he does have feline herpes and stress makes him sick.but full blood work up and everything was fine We don't know what to do anymore he will not eat his own food
