Poor Dexter! That is concerning that he won't eat and has been sleeping all day. If the vomiting and diarrhea has stopped then you could try to get him to eat a small amount of a bland diet. Try a little bit of boiled chicken and see if he will eat that. You could also syringe a little bit of water into his mouth to see if he will drink. If the lethargy, decreased appetite, vomiting, and/or diarrhea continues then he needs to be examined by a vet to determine the cause and treat. He may need some fluids to prevent dehydration and an anti-vomiting medication. Hope he feels better soon!
