...to beat his girlfriend's pet to death.
I'm convinced that anyone who would do that to a house pet would do it to a child.
It's too bad we don't know exactly how long the jerk in question pounded on the little tabby cat. I mean, if we knew that he had kicked and hit it for, say, twelve and a half minutes, then we could leave him in the cage with the Bengal tiger for exactly seven hundred and fifty seconds. I think that would be making the punishment fit the crime exquisitely. He would either learn to be friendly to animals in very short order, or he'd become Purina Cat Chow, machs nichts.
