This is turning into a weird discombobulated day. Didn't get nearly as much done this morning as I meant to, did manage to go to aerobics (where I dropped a bar and scared the crap out of everybody in the class), then came home to notice Harry (the cat) had blood all down both front legs and one back leg. Not on his paws or on his mouth, just his legs. I can't find a wound on him, the other cats are fine, and there's no unexplained dead bodies around. I washed him off in the bathtub (no, it wasn't easy) and still can't find a wound. So unless he has stigmata in addition to kidney disease and arthritis, I have no idea.
