I just got a new kitten a couple of weeks ago, he is 6 1/2 weeks old. He was eating fine the first couple of days of both wet and dry food but as of a week ago now he won't eat anything except for cat treats. I have tried now not giving him anymore cat treats to get him to eat dry and wet food again but he won't. I took him to the vet a couple days after getting him to get his first shots and they would not do the shots because he is under weight. I don't know how to get him to gain weight if he won't eat. I have tried many different kinds of wet and dry food and none have worked. Please help, any advice is greatly appreciated. Thank you
