Some people leave them out all summer depending on temperatures and climate. I take mine out occasionally for a couple of hours(1-4). Really when I am doing stuff in the yard so I can keep a distant eye on them.
Depends what you mean by "Sunning Cage" if you mean a cage that is completely filled with sun, then my answer would be never and not for even a minute. A chameleon should never not have the option to hide in thick vegetation and the shade.
no i always fill his cage that i use for sunning with a thick hibiscus plant where he can choose to bask in the light or hide in the shade i just wanted to know how long people set there chameleons out in the sun
I have a dedicated sunning cage. It is, quite simply, the outside cage that I put my panther in when weather conditions permit. My area does not boast climate temperatures 24 hours a day for even the summer months, so my chameleons cannot live outside for any part of the year.
Basically, I watch the temperatures. When the temps get above 70ish, I put him out. If they go above 90, I bring him in. My cham never stays out when I am not home and never stays out all night. There are too many predators in my area that are completely willing to rip open a screen cage for a tasty treat. In the cities and more congested areas, I would worry about theft. Honestly, I wonder how many people are actually able to leave their animals out for part or all of the year. I am willing to guess it is a small number.
I think the name "sunning cage" quite nicely describes the outside cages many of us maintain for use on sunny/warm days.
When it's nice and warm outside (which is not that often in England!) I put my chameleon outside in exo terra flexarium. It is made of a mesh material and I have filled it with bendy bark and plants. He usually spends the majority of the summer in there when it's warm enough, and I bring him in at night.
