I took out a bag of the results of litterbox cleaning and got to have the reaction of 'why is there blood?' because there was, uh, a very noticable amount on the porch.
Got a flashlight and found an opossum in the cat condo with one of Ringtail's kittens that she just brought over from wherever she'd had them for their first month.
Don't know where two others are, and two are currently in my bathroom so I don't have to worry about them for the rest of the night. (I found them hiding in a corner between said kitty condo-which has clear sides so the poor babies were able to see what was going on--and the porch. They were understandably petrified.)
I've given them half a can of kitten wet food and they've already devoured it. They also have kitten dry food, a bowl of water, a litterbox I don't actually expect them to use both because height to get in and they're young enough to not understand litterboxes anyway, which is why they're in my bathroom. Tile floor.
Oh. Finally managed to remember while actually here. The last time I had been outside before The Incident, there had been plenty of dry food, so there was no need for kitten murder for dinner.
