What is your kitten name? Does the Kitten vomit after eating? If so...the kitten has overeaten. If vomiting repeatedly, stop feeding and contact your veterinarian especially if the kitten's vomit is yellow or frothy, or contains worms.

Kittens are generally weaned around the age of 6 weeks old. If weaned too early, there can be problems with diarrhea and/or vomiting. Then dehydration becomes a risk, and it can be life threatening if left untreated. Was your kitten weaned very early? That can be a reason for the vomiting.

 We had a situation with our kitty where he had swallowed a foam ear plug and it prevented him from holding down his food. It turned out that he had it lodged in his intestine. He had surgery and thank goodness he's terrific. I heard recently that some dogs' stomachs turn with certain activity after eating...could this be a situation with kittys too? Visit your vet. Good luck!

 What are you feeding the kitten,if its milk,most cats are lactose intolerant
