Cerebellar hypoplasia (video of Amy)

[Medusa]

I've got two w/it; one actually has vestibular hypoplasia which affects the hearing and caused Creamsicle to go deaf. She's the worst case. You'd never know Coco Puff has it now. He just goes into a sort of daze like seizure every once in a while. As for how common it is, I have no idea. My old vet thought that it can be caused by the feline herpes virus. I didn't even know what it was called until I became a member of PT, which is why I like it here so much. We learn and teach, we comfort and are comforted.

As disabilities go, it's pretty common, and it can happen to dogs, too. I don't know that anybody can give you a "x out of 1000 births" guesstimate on it, though. Ari is quite severe.

I've personally observed 3 cats with it, out of about 2,000 or so that I have seen, so maybe 1 in a thousand? (I think diabetes is more common than CH.)
