We then move them to cages with 120-200 square inches of floor space. The biggest females will benefit from cages with 1 -2 square feet of floor space. Males can live in cages with one square foot of floor space all their lives. We maintain this species in shelf racks with great success. Ventilation is an important consideration for enclosures for this species.
Rosy boas do best in lower levels of humidity.
Well-ventilated cages allow the water vapor resulting from excretion, respiration, and evaporation to dissipate. Substrate Over the years we have maintained this species on newspaper, aspen bedding, mulch and bark substrates, rocks, and commercially-available brown aquarium gravel. All of these substrates worked adequately. Rosy boas particularly seemed to like cages full of rocks, but such arrangements are difficult to maintain at a satisfactory level of cleanliness and there is considerable risk that the snakes may be injured when they are excavated from the rocks. Our own preference and recommendation is to use aspen bedding.
