Rosy Boa

An adult is comfortable in a secure, front-opening enclosure of at least 90 x 45 x 30 cm with a tight lid, as rosy boas are surprising escape artists that probe for gaps. Provide a dry, burrow-friendly substrate such as aspen or a topsoil and sand mix, at least two snug hides (warm and cool), some flat rocks and low branches to move over, and a modest water bowl. As a rock-desert species they appreciate secure crevices and cover more than open space.

A carnivore fed whole rodents. Offer an appropriately sized frozen-then-thawed mouse (about the width of the snake's body) rather than live prey. Feed juveniles every 5 to 7 days and adults every 10 to 14 days, adjusting to keep good body condition, as rosy boas are prone to obesity if overfed. They naturally fast during cooler months, which is normal for a healthy adult. Always thaw and warm prey thoroughly and avoid handling for a day or two after a meal.

Provide a warm-end basking zone of 29 to 32 C and a cool end of 21 to 24 C, with a night drop that can fall to about 18 to 20 C; control all heat with a thermostat. UVB is not required but a low-output tube can benefit welfare. Keep this desert species dry at around 30 to 50 percent humidity with good ventilation, offering a slightly damp hide only during shedding. Run a 12-hour light cycle, and expect reduced activity and appetite if you provide a natural cool winter period.

Solitary. House rosy boas one per enclosure to avoid feeding competition, stress and the risk of one snake harming another. They are among the most placid snakes and tolerate gentle, regular handling very well, often moving slowly and calmly through the hands, though give rest after feeding and during shedding.

Offer a dry diggable substrate, flat rocks, crevice-like hides and low branches so the boa can burrow, wedge and explore its rocky-desert style habitat. Rearranging cover, adding new hides and occasional novel scents encourage natural exploring in this otherwise sedentary, deliberate snake.
