Basking 88–92°F (31–33°C), ambient 78–85°F (25–29°C), humidity 55–75% (higher for red-tails). A thermal gradient and a humid retreat support shedding and respiration. UVB is optional but beneficial. Low humidity causes stuck sheds and respiratory trouble.
Feed thawed rodents: juveniles every 7–10 days, adults every 2–4 weeks. Overfeeding (a constant food bulge) causes obesity and shortened life — feed to a lean body. Boas have a strong bite and constricting reflex; support the body and avoid feeding in the enclosure-handling confusion. Never feed live prey — it injures the snake.
