Temperature & Humidity

Target a basking surface of 29-32 C and a cool zone of 24-27 C. Turn the heat off at night; temperatures can safely fall to 16 C. Keep humidity below 60 percent, measured with a digital probe hygrometer in the middle of the enclosure, as sustained high humidity makes them unwell.

Enclosure

Size the enclosure as snake length x half length x half length: 60 x 30 x 30 cm for a 61 cm animal, 120 x 60 x 60 cm for one that reaches 112 cm. Front-opening enclosures are easiest to service. Provide 7.5-10 cm of sand or sandy soil so it can burrow, plus several rocks and hides.

Diet & Feeding

In the wild it takes mainly rodents, along with lizards, amphibians, other snakes and birds. In captivity offer thawed frozen mice sized to the snake, warmed to about 38 C, using soft-tipped feeding tongs.

Temperament

Extremely docile and rarely inclined to bite. When disturbed it balls up with the head in the centre and releases foul-smelling musk from the tail base. Its slow movement and small size make it an easy first snake. Keep it singly.

Notes

As a desert species it should never be kept on permanently damp substrate. Its taxonomy is unsettled and coastal populations are treated by some authorities as a separate species, Lichanura orcutti, so confirm locality claims with the seller. Listed on CITES Appendix II as Boidae spp. since 4 February 1977, so no registration certificate is required. The IUCN Red List assesses it as Least Concern.

About Rosy Boa

The Rosy Boa is a small, docile boa from the southwestern US and northwestern Mexico, prized as an easy, beginner-friendly reptile. Adults reach about 43-112 cm.

7 things to know before welcoming a Rosy Boa

1. 1Famously Slow-Moving

   The Rosy Boa is known as one of the slowest-moving snakes in the world. It rarely bolts or thrashes, making it calm and easy to hold. Since sudden movements can still startle it, always handle it gently.

2. 2Calm, Easygoing Temperament

   Rosy Boas have a docile temperament and rarely bite. Once settled in, they tend to tolerate handling well, making them a good choice for first-time snake keepers. That said, individuals vary, so give a newly acquired snake time to adjust before handling it much.

3. 3A Compact Snake

   Adults typically reach only about 43 to 112 cm, so they don't need as much space as larger boa species. A front-opening enclosure makes care easy, and enclosure layout and cleaning are relatively simple.

4. 4Prefers a Dry Habitat

   Native to rocky desert habitat, Rosy Boas prefer dry conditions and dislike excess humidity. Manage substrate, temperature, and humidity carefully to avoid a damp enclosure, and provide a shelter so the snake can retreat and feel secure.

5. 5Nocturnal in Hot Weather, and Quiet

   In hot weather Rosy Boas are mostly active at night and tend to stay hidden and still during the day. They go dormant in winter and are most active in the spring breeding season. They're silent animals, which makes them a manageable pet even in an apartment.

6. 6Feed on a Regular Schedule

   They're typically fed small rodents at a frequency appropriate to their age and size. Keep an eye on feeding response and droppings day to day to monitor their health.

7. 7Prepare Before You Bring One Home

   Before bringing one home, set up an appropriately sized enclosure with heating equipment, a hide, and suitable substrate. After arrival, give the snake a quiet settling-in period before handling it much.
