I got this kitten named smokey a month ago and he loved to eat, He was starved and had worms and very malnutrition. I took him to the vet for all of that. It has been three days since he has eating any food, all he will try to do is drink a little water he is starting to lose what little bit of weight he did gain. I do have a appointment for him this Friday. But what can I do to get something down him. He only weighs 1 pound 2oz. I'm worried. I try to offer him his favorite foods and nothing works, Do I need to try to bottle feed him. he is only 14 weeks old but does not look that old. I appreciate any help Thanks so much.
