I just built a new 2x2x4 aluminum cage. I live in Canada so buying the already made cages is not as easy, so I decided to make my own. I was suprised how easy it was, I built wood cages before and it usually takes me forever and I always run into some kind of problem. This was quick, and fairly cheap, probably about 150$ because I also needed some tools, I could probably make them for under 80 now with the supplies I have. Looks awesome too. Im already thinking of building another 8x4x2 and dividing it into 4 cages, but I am getting ahead of myself, as I dont even have a chameleon to put into this one at the moment. Ill post pictures soon, I still have to put the door on tomorrow.
