Can you use a chameleons cage for a ball python?

Answers:
No, you need at least a 20 gallon tank. Ball pythons require at least a 20 gallon tank, but a larger tank is preferred (30-40 gallons), considering that ball pythons grow to 3-5 feet in length. They require sufficient humidity and heat (humidity between 25%-75%, and heat temperature between 82-86 degrees F). They also require long tanks instead of tall ones, because ball pythons aren't much of climbing. The chameleon's screen cages will not hold the humidity that the snake needs (and humidity levels should be increased while the snake is in the shedding process).
Just a fact that needs to be made: NO HEAT ROCKS! Heat rocks have been known to cause severe burns on snakes!

I wouldn't recommend it, because ball pythons need a certain amount of humidity and a chameleon cage (the types I've seen) have all been screen, preventing the ability to keep the humidity high for your snake.

No I wouldn't. you need to find a large aquarium and a heat rock. A cage won't be able to trap any heat. Snakes are poikilothermic....(cold blooded).they can't maintain thier own body heat.
