Going to he was fine until I got him back from my nieghbors. He isn't eating much I don't know if they overfed him or notCan you take your kitten to the vet? The swelling along with the weird noise is concerning to me. I'm not sure of all the possible causes for this; I think a GI blockage might be one possibility, but there are surely other possible explanations. But, in any case, I think your kitten needs medical attention.
