I used to live with a cat that was eating human hair occasionally. Because my wife has very thick hair, the hair would cause his poop pieces to stay connected, like a chain of poop. He'd sometimes have a piece of poop hanging out of his butt because of this. When he noticed it, he would sit down on it and drag his butt on the floor in an attempt to get rid of the poop. It usually worked, but created these long poop smears on the floor. Suffice to say, we got rid of all our carpets because of that cute little bastard :)
