Last Sunday we found evidence that Pillow had accidentally been locked out the night before (though I thought he could get in by another way). He hid under the bed all that day. Monday he emerged, still nervous. Wednesday I noticed that his abdomen had a lemon-sized abscess. We took him to a vet, who remarked that his (minor) wounds did not look like the result of fighting with another cat; he asked whether there are raccoons in our neighborhood. (Yes.)
With his belly shaved, and bits of rubber hose poking out of it, Pillow from some angles looks like a cow. But I’m not gonna say that to his face.
