My Jasper had seizures occasionally after neutering. They scared the heck out of me when he had them but he did not seem to suffer. He would be a bit clingy and tired afterward. I think they scared him. He would have them every couple of months at the beginning and then less frequently as he aged. I Think it was from the anethesia. He did live a very heathy life other than this issue and lived to the age of 15.
