We have a male siamese about 5 months old. About a month ago, he had a knot on his right hind hip, and it was there for about a week and then went away. We didn't think anymore about it until now, he can hardly walk. When he walks, his feet turn under and then he just keeps trying. We can't afford a huge vet bill, and wanted to see what you think it could be.
This could be a neurological problem which should be delt with at the vet. Your cat should have some blood tests and x-rays performed. Good luck, vetcare
