Probably no gun in the house. But I can tell you, a cat can cause an incredible amount of harm to a human.
Not my cats.
But then again, I routinely snip the front and rear legs off of all my animals.
I detest chasing them around the house, so it's the only humane thing to do. Meet my cat "Hot Dog", and my dog "Door Matt", and my other cat "Mr. Stationary".
