Pet's info: Cat | American Shorthair | Male | neutered | 1 year and 1 month old | 11 lbs
Hello, Kovu does have a vet visit tomorrow because of decreased appetite and weight loss. I was just wanting to ease my mind because I’m so worried for him. I was wondering, could this possibly be caused from switching to adult food? He was on Royal Canin kitten instinctive and I switched him to Royal Canin American Shorthair food about a month early. (he was 11 months old but seemed to not mind eating it) I found out he will eat now, only if I feed fancy feast.I’d Rather feed good quality food

I wouldn't think that a decrease in appetite and weight loss would result from a diet change. Some cats can be quite picky and will stop eating a food they previously liked or be hesitant to try a new food, but eventually these cats will eat once they get hungry enough and picky eating should not result in significant weight loss. I wouldn't be concerned about changing to an adult food in an 11 month old cat either - Kovu was probably very close to his adult height by that point. I think seeing your veterinarian to have Kovu's weight checked and for a complete physical exam sounds like a great idea, and if they feel he is in good health you can discuss trying to find good quality diet that he seems to like and then monitor his weight closely.
