the Humane Society listed them both as snowshoe, a derivative of Siamese breed. Toby's coloration and personality seems pretty par for the breed. Havoc doesn't really look typical snowshoe to me, but he's such a sweetie I don't care. Havoc was the one I was after, since he looked so pitiful with his gimpy leg, runny eye, and dirty ears, plus he jumped up on my leg like a dog and begged for attention. Toby was just too cute to pass up and the adoption fee was the same for 1 or 2 cats= no brainer! They really do have opposite personalities. Toby is quiet and laid back, and Havoc is a hyper chatterbox.
