A feline which is naturally insane or has had one too many knocks to the head. Just not all there. Symptoms include acting like a schizo at all times, biting and scratching until you bleed, destroying your house and terrorising the dog.

Your only means of protection is to surround yourself with water (I.e get in the bath), have food to hand and only pet him when he decides to snooze.
