Demon spawn

I don't much care for cats.  Granted I did have one when I was younger, but still not a huge fan.  This is my brother's cat Oreo, aka: demon cat.

Much as he appears in this picture, he will try to eat your face off.  He has been fixed, but he still pees on everything (I'm lost a purse and had to wash multiple items of clothing thanks to him).  He will attacks for no apparent reason.  He will let you pet him and when he is bored or done he claws you then walks off.  While I understand that some of this behavior is normal for cats, I still believe he is a demon in cat skin.  But when he climbs into my lap and starts purring, I still can't resist him.
