A Boxer is a Dog, I thought.

My cats are boxing. They do this thing where they sit on the tallest surface they can find, face off and stare each other down while standing on their back legs with their dukes up. And then every once in a while, one will punch the other, the one who gets punched punches back, and then they get in a headlock (just like regular boxers) until they break it up and start over. It is seriously hilarious. I took a couple pictures, but I'm sure it won't capture the humor of the routine.
