Problems with huge cages....
Yeah, they can be pretty hard to regulate (temp and humidity). If you do house 2 snakes together, make sure there are 4 hide boxes and 2 water dishes. Snakes are SOLITARY! Therefore, if they find an awesome place to be where prey comes dancing along every week, they are going to stay put and the last thing they want to see is another stupid snake in its territory! Housing snakes together isn't a good idea in my books. 2 smaller cages is the best option.
