OOH OOH I KNOW!! She's likely a snowshoe, which is what you get when you mix a Siamese cat with a tabby or calico. They look like Siamese cats, but they have white feet and frequently white blotches on them in random places. I've had several, including the cat I've posted like, 20 pages back. But Tardar has an underbite or something that gives that frowny face. Which happens to be amazing.
