Shadow is a cutie. If he isn’t eating well for several days I strongly recommend a vet visit. Cats can stop eating whenever they don’t feel well which could be anything from a mild infection to a more serious disease. Since he has now started vomiting he may become dehydrated quickly. A veterinarian can perform a physical exam and then make recommendations on what other diagnostics or treatments they might recommend to help Shadow. I hope he’s better soon.
