Also very important....
You're very welcome, Patrick.

All too often, people receive bad care advice from well-meaning sellers who just don't know any better.
Since she has been having troubles gripping, her bones may also be weak, so I would not handle her.
By making the needed changes, your princess won't become one of those heartbreaking chams.
Very important for calcium absorbtion is a good UVB bulb, like the Reptisun 5.0, which should be replaced with a new one every 6 months. (It will still light up just fine but it stops giving off enough UVB for your cham's needs.)
Chams can't use the calcium they ingest without a UVB source.
Daily exposure to at least an hour of natural sunlight actually replaces the need for UVB bulbs and D3 supplements.
Vitamin D3, used only 2x a month, helps calcium to be absorbed--but it should only be given 2x a month. Too much D3 supplement is harmful.
Natural sunlight is excellent--better than UVB bulbs.
Your cham's body actually makes a very safe amount of natural D3 from spending time in unfiltered sunlight. (Not sunlight that passes through glass or plastic--no UVB in that.)
If your cham can be safely taken outdoors on a plant for a while while you watch her carefully, her body will actually make some of its own D3.
The temperatures need to be OK for her and you would be very surprised at how quickly a cham can disappear if you go inside for "only a minute" to answer a phone, use the bathroom, etc.
If you can get some Phoenixworms or Calciworms, they will also help your cham to catch up on calcium.
Phoenixworms are especially high in calcium.
Silkworms, hornworms, dubias and blue bottle flies are other foods which will add variety and different nutrients to your cham's diet.
The Panther caresheet that I gave you a link to is a good one to look over and see if everything is right with her care.
You need to be careful not to give too many or too few vitamins.
The best way to ensure that your chameleon is getting all the nutrients it needs is this:
Feed a variety of feeder insects --not just 1 or 2 types of insects.
Feed your feeder insects a very nutritious diet, so that they provide your cham with good nutrition. (More info here:

Use calcium and multivitamin supplements to ensure that no nutrient is missing from your cham's diet but not as a substitute for good feeder nutrition and variety.
Chams don't enjoy handling and many chams are extremely stressed out by it but some will tolerate a small amount of handling.
It depends on the cham--each one has his/her own personality.
