Check this out, I built it myself, all oak plywood and solids. The individual sections are all interconnected with 4" PVC that can be closed off at each cage section. Currently have all sections closed off for gravid females. I Have two of these and connect the four vertical cages on each side as a "set" with a male and his harem. The two cages allow me to have up to four of these "sets" for breeding.
