I have a male retic who is about 4 feet. He is my only retic but i plan to add one more next year and sure enough more after that.

I keep my tic in a 41qt tub but I know he will need much more space fast. So I want to get him into a bigger cage but i dont know what i want.

I have been looking into cages here. www.monster-cages.com
I like them but i find them a bit expensive.

Can anyone here please show me how to make a homemade cage? I have never built one, just a wooden rack for my ball pythons. So I dont know what materials would I use. Can anyone be of any help?
