I am sorry to hear this, I lost my first cat to a fit, and I know how hard they are to witness, espeically when there was no real sign before. I dont think there was anything you could have done, and at least this way he wasn't prodded and poked about, and was with the people he loved. I am glad the CP people have been able to give you some comfort, and that you got some enjoyment with the kittens. I am sure Josh will have a hand in your next furbabe. RIP little one
