I have a kitten (10 mo.)that began with a weakness in his back legs at about 3-4 mos. and now it has progressed to weakness in his front legs at the lower joints, and his head bobs like a palsy patient. His vet suspected that it was prob. a genetic issue, since I found out after his problems began that his parents were brother & sister. Do you have any suggestions or ideas?
This could be cerebellar hypoplasia which is congenital dz. There are other possibilites. Have you considereda neurologist? vetcare
