I have a male Persian cat that looooooves to rub himself all over my smoke laden clothes when I get home from the lounge. He also rubs up on and pretty much owns into any box of cigars I have out. Must be something about them they like.
My dog Tyler used to love the eat cigar ash. Wherever you would drop it...he was there to grab it up. Even get the point where you would kick it with his foot to make sure wasn't hot
