I usually do the 2 week period to acclimate and get use to their new environment, when i get a new baby chameleon. when you do put him back in the cage i suggest put him on the ground and let him climb back up to his perches on his own my baby veiled and panther i once let walk back on the vine they got too excited and fell 2 inches so I now just let them walk off my hand on the ground so they can walk up on thier own and not worry about losing foot holds on the branches.
