My 5 month old kitten, has just come up to me meowing away, he seems to have hurt the right hand side on his side by his hip. If I stroke him he cries out, he's taken him off to lie on the couch, (he jumped up 3 legged on to the couch), he's curled into a ball and seems to be breathing heavily.
He has been fine, for the last hour or so, he's been asleep on my bed.
Does anyone know if he's just got cramp, or do I need to get him to a vet asap?
