Wow, neat set ups, Whiskey. =}
And awe, you have a Chinese Crested too? ^_^
*points to dog with pink sweater*
We have two Cresties also. =D
This was Romulus, Vulcan, and Bootstrap's old cage, when they were younger.
I just combined two Marchioro Tommy K's together with zip ties.
One of the shelves had an elbow tube, and one of the shelves had a three-way tube.

This was their new Critter Nation when we first got it, so it didn't have much stuff in it when I took the picture.
Pocket Monkey lives in there with them now, also.

And, I know this is a rat guild, but here is my two cavy boys', Dobby and Kippert, lil' C&C cage (only 37" x 35" presently). I just zip tied the metal grids together and used coroplast for the base.
I plan on adding a second level to it, but they hate using ramps. ^^;
