I had an orange tabby that had dark markings on his head that looked like horns and he was a real devil he would sneak under my blanket and pounce on my feet wrapping his paws/claws and biting at the same time. and he would also run around the house real fast until he was at full speed then run straight up the door jam and hang from the top of it with his rear legs dangling down. So I named him Lucipher gawd I miss that cat. always kept me on my toes
