hi, i think you are talking about my tegu cage.
here is a recent pic of it.

there are 2 things i didnt plan from the start. one thing
is to place some support in for the middle ground (from the
bottom) and some support for the top of the cage, what is
necessary if you want to place some more glass-cages on
top of the tegu cage, like i do.
the other thing is, on the middle floor i left some place
towards the glass to have better air circulation, and i
only put a short board there to keep the ground substrate
on the upper floor, experience showed me, that the tegu
used the space between glass and middle floor, to make
stagediving instead of using the ramp to get to the lower
floor. i fixed that problem now.
i hope my english is good enough to understand what i mean. 
ohh and thanks for the praise once more.
