Cat Man - the human 'tiger' who enjoys climbing trees and eats raw meat every day

As obsessions go this has to be one of the weirdest known to man - someone who would voluntarily file his teeth, split his lip and undergo extensive facial surgery - to turn himself into a 'human tiger'.

Dennis Avner, 50, is descended from American Indians, and has spent 'an uncalculated amount' of money on making himself look like a big cat, after a discussion with a Native chief who inspired him to 'follow the ways of the tiger'.

Avner's body modification operations have included bifurcation (splitting) of his upper lip, surgical pointing of the ears, sillicone cheek and forehead implants, tooth filing, tattoos, and facial piercing - to which whiskers can be attached.
