I'm going to try and find the smallest mouse I can. Our only pet store is Petco...T_T...which killed all of our other awesome pet stores which sold live fuzzies and hoppers a couple years ago...Petco gets their shipments of mice in on Wednesdays, which happens to be Petrie's feeding day, so I'm going to go every wednesday and try ad get their smallest mice, which they usually keep in the back.

Just leave the live mouse in his tank for an hour plus and he will probably get the idea.
