Well after much stress getting Lennie to start feeding this spring, a few weeks ago he slammed a live rat. At the time i figured my problems were over- until i went to the pet store only to realize that this place doesn't understand the need to keep feeders in stock. long story short, i ordered a big pack of frozen rats from big cheese and Lennie took one first try. Last year he never seemed to want to make the switch, so i am really happy about this :D
