outdoor enclosure
I too live in S. Florida and have had sucess keeping veilds and panthers outdoors. The natural, unfiltered sunlight is 100 times better than any artificial light. As long as your cham has access to shade and sun, he will be able to thermoregulate just as he would in nature. I agree with the previous posts about making the enclosure insect proof, you don't want him eating insects that have been exposed to pesticides or baby brown anoles who will enter the cage to drink from your mister. The other great thing about outdoor cages is you don't have to worry about water collection. I have a garden hose on an auto timer hooked up to a misting wand aimed at the cage. The only worry is that you have to check weather.com every day in winter to check what the overnight low will be. Most nights it stays in the 70's here, but two or three times a year it dips into the 50's or 60's at night. If the forcast is for lower than 65 I take my chams indoors until it warms up again. I never have to keep them in for more than a couple of days. Your veiled can tolerate overnight lows in the 60's, but forcasts aren't always completely acurate, that's why I bring mine in even if the forcast is for low 60's. Good luck, your cham will love it outside.
