If there is a way there chameleons have a will. I have seen mine in position's that do not even seem possible. They sure do put on some nice entertainment.
My girl today hung from her tail only, grabbed the deli cup of roaches, lifted it to her face and ate. when she shoot her tongue in the position..she shaked the cup violently each shot. how she hit them idk.
I've been picking mine up by the tail for fun. When I put my finger under the tail it will curl around and then "lift off". They'll just hang calmly and look around. It's funny.
