Don't know, but you must be very careful about insects doing harm to your animals...ants and flies in particular. Ticks and mites could also be a problem. Animal predators such as Raccoons could be an issue as well, should the cage not be secure and sturdy enough.
Be sure to allow any animal a good place to escape excessive heat/the elements. Use an infrared temp gun to make sure a "sunny spot" isn't really a deadly inferno.
