Please take your cat to the vets. Once cats stop eating, it’s a nad sign that something is wrong. If your car is still eating, then maybe it’s the food.

Cats are finicky. My cat refuses to eat anything other than Fancy feast dry foos & a special friskies seafood gravy. lol

Try feeding your cat canned food or gravy too. Buy only one can of a brand until you find one your cat likes.
