UPDATE: received two replies from the pet store. Just a little back info...I emailed them with an update of the Chameleons health, and asked if they wanted her returned. I also sent a HUGE paragraph basically telling them everything they were doing wrong in caring for Chameleons. (Very politely of course.) It covered substrate, lighting, feeding, and supplementing which were all WAY off.

First reply is from the owner of the store:

Hi Julia,
Thanks so much for the update and all the research you have done! Congratulations on saving the girl. She is yours to keep! By the way, there was never a gray area as far as you keeping the Chameleon. I will pass this email onto Kreig. (Reptile expert.) He will be very interested in everything that you have discovered.
Thanks again for letting us know.
Jeannie

Then a reply from Kreig the reptile expert:

Hi Julia.
Thanks for the update on the Chameleon . I'm glad to hear she is doing much better.
I have been re-evaluating how I do my chameleons in the shop , and for our future shopas well, so I appreciate the information you sent. I have been trying to get more detailed information about the bulbs we use from my suppliers to help with better choices in their usage.This is how the hobby and husbandry on the care of reptiles advances , with people working together to figure out the best care possible for these creatures.
Again thanks.
Have a great Thanksgiving.

I really hope that these guys are not just doing the customer is always right thing....and that they do make improvements. I will check up on them in several months and see if anything changes.
