Can you find any hornworms near by? I would think her eating one of those would be rejuvenating.. and do you know how to open her mouth correctly? I'm surprised no one has tried to explain how to do it correctly..Do you have an eye dripper or something? I just read that you can try to slide a credit card into a chameleons mouth to help open it, then I would try dripping droplets onto her lips and I'd hope she'd try to lick them up or swallow them...Looks like she's hanging on by a thread..
Edit: did you ever get some silkworms?
