Dennis-
I only put them outside on there ficus trees or plants from there cages when I am cleaning, and I am outside watching them and keeping an eye out for large birds with the exception of my ambilobe he tells me when he wants to go outside and has his own outside tree. LOL! If you are going to keep them outside not in cages where they would be protected by the screen, make sure you are outside watching them. The more unfiltered sun you can give your chameleon the better. When I put them outside unwatched they are caged. I use plants because it gives the chameleon a place to be exposed to the sun and a place to be shaded from the sun. Also you don't want to place them in direct sun, they must have a place that has access to shade, and water if you are keeping them outside to prevent dehydration. As long as you provide these things they can be outside all day long. You will notice there reaction when outside, they love it, and in young growing chameleons they tend to grow better. If you are exposing them to natural sun for more then 4-5 days out of the week you should use a vitamin/calcium dust that does not have D3 in it, this means unfiltered sunlight (light that does not pass through windows(glass) or acrylic/plastic). So the main thing when keeping them outside is to provide a place to bask, a shaded area, and a water source.
P.S. One more thing, my male panthers like to roam, and will walk off there trees in search of bugs and there female mates, so this is also a good reason to cage them when outside.
