Oh I am so sorry!!

It's not uncommon for pets to develop neurological problems. I'd definately take him to the vet and explain the situation.

I was attacked in the face by one of my cats. I took him to the vet, fearing he had rabies. Turns out he had a hormonal imbalance and just snapped. Unfortuantely I was in his path. (He leapt off the bed right at my face )

He was supposed to be fixed as a kitten, and the vet removed his hernia, but never fixed him. For years we had no clue. He was fixed immediately after the incident and he was fine.
