Then The Professor tells me in detail how Warrior Princess only got sick twice last night, both times in the hallway, and how he cleaned up right away. I let him tell me twice, and then asked "So you didn't have to clean any more up today?"

"No," he says. WP was fine today.

That's strange, I observed. "There were two big puddles of cat vomit by the door when I left this morning." "Well they weren't there when I got up," was his reply.

I turn on all the lights by the door. Sure enough, the crusty remains of stains are still there. He says it must have been one of my cats, that WP was completely cleaned out when he went to bed. Therefore I should clean it up.

Right. There was only one cat vomiting last night, and it wasn't either of mine. I pointedly observe that I'm not cleaning up the remains of his cat's Professor-induced illness. He relented and said he'd get to it later. Later has not come yet.

I'm not even going to wonder about what happened to the bulk of the regurgitate that was on the carpet. At least whoever took care of it kept it down the second time.
