I started giving Popsie some skin and coat formula oil about a week ago. I wonder if that is what's been messing with his appetite. It's specifcally for pets. I give it to him everyday like the directions say to. Should I stop giving to him?
If you have given him something new and noticed a negative change, I would definitely stop giving it to him. Cats have very sensitive systems, with some cats tolerating things more than others.
