I haven't reported on this in awhile, here's an update:
The male has been sold to (I'm told) an experienced keeper. He knew a lot about chameleons and purchased about $400 worth of additional equipment and supplies according to the manager at the store. Hopefully he is in a great new home.
Our gravid girl, however, remains in the back and is, again, in a glass tank.

Apparently the district manager came through and didn't like our set-up for her and made them change it. She looks okay, although I am not pleased that they do seem to ignore my request for some sort of drip system. They have a water dish and spray her throughout the day. How much this or any care happens for her is (I'm certain) dependent on who is working that day or shift.
Unfortunately Frank and I have determined that (for a number of reasons) bringing her home is not a good idea for us right now. We have also agreed that we would become advocates for her and try to find someone who would be a good care provider and understands what's coming up. That's a hard person to find!
On a more encouraging note, the manager told me yesterday that she will not be ordering any more chameleons. This has been too stressful for her and she doesn't believe a store like Petsmart should carry animals like these. She really does care but is, unfortunately, under the thumb and watchful eye of her superiors.
