These have all been really funny thanks for the chuckles.
I remembered another thing my freak cat likes to eat - Catlax. You know, the yucky paste for cats to help with hairballs that you normally have to force them to take? Well Charlie will lick it straight off my hand.
Those with dogs reminded me that ours has a taste for welding gloves which can't be good for his digestion. He also likes to run around with a bath towel in his mouth (he has his own supply)!!
