I haven't witnessed my chameleon shed for a good month in a half. Should I be worried? She's eating fine and I mist the cage frequently, along with a drip system set up occasionally (though I've never once seen her get excited about the water).
I'm going to say she's at an adult age or close, but I've had her for 4 months and she's doubled in size.
The past times she's shed it's taken her a full day or two to get through it, so I don't think she shed without me knowing. Her stool is good, weight normal, she's got two plants in the cage, a heat light and UVB light. I occasionally set up a UVA light for her, but it's not always on.
I dust her crickets with calcium about once a week and I put her meal worms in a dish with calcium at the bottom. She takes two bites out of an apple slice every few days and I feed her a wax worm once a week.
Picture below is her a few weeks ago.
