My Coco Puff had a seizure when I first moved into this house. It's scary, I know. I've not had experience w/seizures in cats that much, other than the one w/Coco Puff but my Peke-a-poo Charmin had seizures and was on medication all her life. If Braveheart has another one, softly call his name as you stroke him and it will help to bring him out of the seizure sooner. And, of course, keep him calm for a little while afterwards. I'm sorry this is happening to him, poor boy. (and you)
