I either feed my dumpy by hand (hold the bug in front of him until he attacks) or place the frog in a plastic container and let the bugs wonder around until he eats them all. Otherwise the bugs just escape into his well-planted enclosure and I never see if they are eaten.

also, does the school have heating and/or air-conditioning during nights and weekends? I think some schools shut down even while school is in session. This could result in your frog being uncomfortable.

Best of luck!
