There seems to be a group here who knows when and where to get wild caught chameleons. While these animals are not suitable for a beginners, it would be nice to know where you get this information. Do you just know importers or is it posted somewhere?
I don't know about the States but here in Ontario the store I dealt with for over 20 years always brings some in. You could also get them at the reptile expos here.
I always liked getting WC's for breeding because I could be reasonably sure that they weren't related.
I don't deal with WC because they might die and I don't want to go through that but there are various importers here in the states. Some of them are here on the forums, although they aren't very active here.
