My male panther cham was 2.5-3 months old when I got him, and scarfed back 10 2 week old crickets the first day, 15 the next, and regularly ate 15-20 crickets after that. Now at over 4 months old he pounds back 15-20 3 week crickets, a few soldier fly larvae, silkworms and maybe a few other feeders (handful of bluebottles, a waxworm or two, a butterworm, or a few stick bugs- whatever I have on hand) A DAY. My god, he is eating me out of house and home. However, he has also quintupled his size in 5-6 weeks, so at least it's going to good use.
