I want to free roam my chameleon when I get one. I don't know how to feed crickets with out moving the Cham into a screened cage to eat them. I feed crickets to my red eyed frogs. Three times now I have had them get out and invade my tort, Uro and my second floor renters homes. Not only imvade their homes, but i have baby crickets popping up in two of the places, and i now have a fourth invasion. I can't have that. How do you feed them and not get them all over your house. Are they a must? I have read about feeder cups, but don't understand how the crickets stay in them and not get out. Any help appreciated.
