Cats rock - I have a six month old 1/2 siamese and half something else. He has webbed feet and a flap of skin that rins from his elbows to his waist (think flying squirrel).
He adopted me by hopping into my truck at a fast food place and looked at me like "ok, lets go home".
He play's fetch, buries his toys and actually "barks" when the door bell rings. A true "CatDog". His name is Alf.
