A friend asked if I ever heard of ferrets being blood suckers. I said:
"No, it probably is a wise tail."  To my amazement this was on the
internet. "They rarely devour the animals which they attack, but kill
them and suck their blood. Their slender bodies enable them to enter
burrows, but unless muzzled the ferrets are apt to leave their victims
behind after sucking their blood."
