My chameleon spent most of his time between 2 pot plants rather than in a terrarium. When he started molting, he went walk-abouts in our apartment about 3 times. Up the curtain, towards the kitchen, around the living area... he'd go missing for a day or 2 at a time. I then decided to lock him in his terrarium while he was molting. It took a LONG time. When I thought he was just about done (Only his little head to go), I left him in his pot plants - that was his escape opportunity. He's only a little guy - 15cm including tail!
