A vet is your best bet. A plastic container isn't a great idea for housing any chameleon. A cage by a window does him no good. He needs uv light which he isn't getting by sitting by the window. Uv doesn't penetrate thru glass and screen. The cage by window if in the sun will heat up alot...
Will minwax polyshades work as a waterproofer on a cage. I'm building a wood frame with screen inserts. I know the misting and humidity will affect untreated wood. Can I use this to coat the entire wood section of cage?
