Picked up my baby veiled chameleon today after doing plenty of research. He's living in an exoterra flexarium, its filled with sticks and plants to climb on but when he tried to climb onto the plastic in the flexarium he couldnt grip and fell a fair distance to the bottom of his enclosure. He seems fine and unhurt and has climbed his way back up but next time he might not be as lucky, will he learn or is there anyway to prevent this happening again, was thinking of wrapping some sand paper around them?
