Heres some of my Chipmunks aviary houses, they are all similar inside, i have their food bowls, nest boxes and litter trays. The first two houses were wire meshed inside since they are part of the original structure and if the Chippies chewed through the wood they would escape. The newer houses are built completely inside the aviaries so we only meshed where each house joined onto the another so the Chipmunks can't chew into the other house.
