Euphemism for having sex. You don't want your cat staring you down in the middle of the act, so you put them in the bathroom.

"Did you hear? Kathy and Derek put the cat in the bathroom last night!"

When a man tries to put his balls into somebody's asshole.

Example: I tried the cat in the bathtub last night. What is that? I tried to put my balls in my wife's ass. How was that? You every try putting a cat in the bathtub?
