How exactly could you free range a chameleon in a bedroom? Water, food, humidity, heat. How is their temper when you do that? Do they wander off or stay in the plants( I want to do a ceiling venture from my bed going up. This is what I have so far
What will keep him settled a bit is if parts of the FR are close to a window, especially if the sun is coming through it! He'll sit and enjoy it for hours!
But why do you think seeing them through the window might stress him out? My guy sits on his mini FR in the window and just looks out for hours, trees, dog next door, birds and planes flying over head.. Sometimes he ducks a bit from the overhead objects but he doesn't really stress or freak out over it.
I recommend giving it a try, I think he'll love it!
