Zippy-Kat, what a horrible thing to have to go through - for Tom and for y'all, his humans. I can't speak for that dog's owners, and I KNOW NO ONE on Pet Talk is like this, but sadly some people actually train their dogs to attack cats - they think it's funny. Fortunately, that "shaking" that attacking animals do stuns the animal being attacked so that they feel no fear or pain, so Tom's demise was not as horrible for him as it may seem to us.
