Hi,

Could you possibly build some kind of shelving system so they could be seperated more?

Or possibly replacing the light in the top enclosure with an LED based solution to keep the temps down on the cool end? **edit** Re-read the descriptions and saw it was a split cage on top so this isn't much use to you - will leave it in just incase it helps later readers. **end edit**

Only other thing I can think of is more insulation between them - have you contacted the cage manufacturers? If they were meant to be stacked and use RHP's then surely they must have had to solve this before?
