This can be achieved with a basking lamp and several climbing branches. This can be achieved through frequent daily misting. Fluorescent ultraviolet light should be provided for 12-14 hours each day. Items such as crickets, superworms, waxworms, butterworms, and small mealworms all make great food items. Something to remember when feeding your pet is the gut-loading of the insects.
Chameleons naturally drink off of leaves after it has rained.
Misting the habitat each day will simulate natural rains and the chameleons will lap water from the leaves. You can also set up a drip system on top of the habitat that allows a single drip of water to fall every couple seconds. The drip system works best when the water falls onto a leaf allowing the chameleon to drink at their leisure. Successful permanent maintenance requires at least a 25 gallon terrarium. A screen lid is essential for proper air exchange.
