The geckos and anoles are wild caught in Florida - there's no question about that. The house geckos are collected in urban settings (because that's where they're most common) where they've been exposed to all kinds of pesticides and household chemicals.
There's no way I'd ever feed any of these to one of my reptiles. Besides the issue of not knowing what the lizards were exposed to before they were caught, I would never feed a reptile to another reptile just because of the possibility of transmitting lizard-specific disease. It's totally possible that wild caught lizards have fewer parasites than captive bred, but it also seems silly to risk feeding your cham a lizard that may be carrying a disease that affects reptiles, and can easily jump from one species to another. I mean, we recommend quarantining any new arrivals in our collections, right? How could feeding a new arrival to my cham be safer?
