This can be provided by the use of a Vita-lite, Zoomed Iguana or ReptiSun light, or a Lumichrome 1xxx light. Also, the fluorescent lights produce more UV A, essential for proper behavior, feeding and reproduction, than do incandescents. These desert lizards require a hot, dry environment. Lower nighttime temperatures, down to 65 F, can be sustained by adults. While a few drops splashed from the melting ice cubes is all right, the cage bottom should otherwise be kept dry.
Chameleons can also be hand-fed water by offering the tip of an eyedropper or syringe hub.
As Veileds are desert chameleons, they have little need for humidity other than that already provided by the plant. Supplement prey with a multivitamin with an appropriate level of calcium and Vitamin D3. It is absolutely essential that you feed your prey animals properly. For crickets, use poultry feed or tropical fish flakes mixed with reptile vitamins, with fruit offered for necessary moisture. Adults will also feed on live ficus and pothos leaves.
