Yup! I "only" have a dozen bps, and it can be pretty painful. Especially when I've got somebody who hasn't eaten in 5 months and won't even give a live mouse the time of day. Or when I've thawed 9 rodents and nobody wants the last 3, and I don't want to waste them. So I spend an hour dangling them in front of apathetic snakes, and wind up throwing 2 of them out anyway...
