My only opportunity to get him to a vet is tomorrow a.m., unless I drive for an hour to the animal emergency clinic in the "city". I don't think that's necessary, because this does not look like a cat in pain. He looks and acts completely normal. He just beat up his brother to get him out of the window he favors. He threw himself on his back in front of me while ago to get me to rub him. He's eating and drinking normally.

He may be having pain when he urinates, but he's not in pain otherwise. Thanks for the advice, though.
