My husband and I came home this afternoon to find Chloe limping. She is favoring her left front paw, but there are no visible signs of anything wrong. We are guessing, that being the daredevil that she is, she probably jumped down from either the top of the china cabinet or the top of a bookshelf straight to the floor (without using a half-way point). Anyway, we're watching it, and if there is no improvement tomorrow, we'll be off to the vet.
