Yep, that’s a drowned mouse in a toilet. Thank you, cat.
And this is a pair of dead robins in the front hallway. One is decapitated. The other is intact. The perpetrator can be seen lurking in the background.
The pièce de résistance. Half of a squirrel, its paws, its face, and its liver artistically arranged on the landing. I have no idea how he got it to appear as if the front half of the squirrel had teleported through the floor.
Look at that face. Butter wouldn't melt!
