I would like to build a muilt unit lizard cage. Im running out of steam for this project because of the cost. Im at the point now of just using clear rubbermaid totes and shelving. I would like to instead of it being one big unit for them to be stackable so i can take them apart if need be. I would like 2 cages to be 8ft long 3ft high and 4ft wide. The rest being 4ft X 3ft X 4ft. They will need to have doors or be on rollers so i can pull them out to.clean them There also needs to be enough space for heat lamps and such. any pics, web links anything is great. I really what to get this done with a minimal cost. The more costly the less likliy DH will go for it.
