My personal theory is that it's a poor unfortunate creature who died upon entry into the Kitty Litter Box. He happened to be crawling past, caught a whiff of the nasty fumes, passed out, and was later discovered by my lovely wife ... who is suspicious because of the fact that it was found in the Kitty Litter Box.
It's about 5/16" of an inch across; those are grains of cat litter next to it. It's noticeably smaller than a penny, and was slightly larger than the 1/4" spaces between the tile.
So the question for all you animal experts: Did this thing come from our cat? Do we need to take it to an honest-to-goodness Vet for treatment? Or is this "ok?"
Thanks in advance.
