mine likes eating everything, and rolling in anything, was getting washed 3 times a week and yes, I know you aren't supposed too however the stench means that you cannot be in the same room as him, once he has covered himself, and swimming in pools/rivers does nothing to water down the smell.
worst yet was when he found a rotting fox corpse, and was rolling in it and when I chased him off him would pick it up by its (rotting) head and run off with it trailing the corpse behind him, with bits falling off until at a safe distance and do it again. **** got jetwashed for that one.
