Aww, I had a cage full of pet crickets there for a while - I'd been wandering through PetSmart and happened upon all those bags of live crickets they sell as food for other critters, and I think it took about 15 seconds of examining them and their cute little crickety faces before I was buying a bag o' bugs, a cricket cage, and a special jar of cricket food ... they were almost as much fun as an ant farm and they really COULD chow down when you fed them something they liked ...
Don't watch it if you have a weak stomach.
