Overview
- Rests on a single source
- Only expert, clinic or hobby sources
Sand boas are docile, slow-moving, stout-bodied snakes with small eyes and a blunt tail 1. They rarely bite, preferring to ball up or escape, and they're popular for their many morphs 1. Sand boas are usually 2 to 3 feet long, and by two years old females are much larger than males 1. They live 15 to 20 years, sometimes longer 1.
Natural history
The Kenyan sand boa lives in Egypt, Sudan, South Sudan, Ethiopia, Eritrea, Kenya, Tanzania and Somalia 2. Sand boas are nocturnal burrowers of dry country with partly sandy soil, not pure sand. In captivity you will often see only a head poking out of the substrate 1. Wild sand boas ambush rodents, lizards and small birds 1.
Enclosure
- Rests on a single source
- Only expert, clinic or hobby sources
- Size. A 10- to 20-gallon enclosure is a good size, and larger is better 1.
- Floor space beats height 1.
- Opaque tubs work well. Ventilated sweater boxes work especially well, because the solid walls feel secure 1.
- Hides. Two hides, warm and cool, if you don't provide a burrowing substrate 1.
- Rocks. These add enrichment 1.
Temperature & lighting

| Target 1 | |
|---|---|
| Gradient | 75–85°F |
| Warmest spot | no more than 90°F |
Heat from below with an under-tank heater, heat cable or heat tape on a thermostat, so the burrowed snake can warm up 1. UVB isn't required for whole-prey eaters, but Chicago Exotics recommends a low-output UVB bulb for health and natural behavior 1.
Humidity

Keep humidity under 50%. Sand boas do poorly in damp conditions 1. Ventilation and a water bowl on the cool side are usually enough 1.
Substrate
- Rests on a single source
- Only expert, clinic or hobby sources
Sand boas need to burrow. Use 2 to 4 inches of aspen, stirred daily and changed weekly 1. Despite the name, pure sand carries risks of impaction and abrasion. For a naturalistic setup, a 60–70% topsoil to 30–40% play sand mix is acceptable if monitored 1. Never use pine or cedar 1.
Diet & supplementation
- Rests on a single source
- Only expert, clinic or hobby sources
- Prey. Frozen-thawed mice, fed after dusk 1.
- Size. Sand boas prefer smaller meals than their size suggests. Nestling mice are a favorite 1.
- Babies. Pinkies or pinky parts 1.
- Adults. Small or hopper mice 1.
- How often. Hatchlings every 5 to 7 days, adults small meals every 7 to 10 days 1.
Despite their slow movement, they are enthusiastic feeders, so offer food with tongs 1.
Handling & temperament
Sand boas are docile and rarely bite 1. Lift them gently out of the substrate. Wash your hands afterwards: reptiles and feeder rodents can carry Salmonella 5.
Health
- Only expert, clinic or hobby sources
Common issues
- Respiratory infections, often linked to cold or dirty enclosures, and in sand boas to damp conditions 14.
- Impaction or abrasions from unsuitable sand 1.
When to see a vet
Call your vet for stuck shed or eye caps that won't come off, noisy breathing, weight loss, lumps or a month without food. Open-mouth breathing or an unresponsive snake is an emergency 6.
Breeding overview
Kenyan sand boas give birth to live young 2. Sexing by probing should be done by an experienced keeper or vet 1.
Genetics & morphs
- Rests on a single source
- Only expert, clinic or hobby sources
Selective breeding has produced many colors and patterns in sand boas 1.
Legal & ethics
- Rests on a single source
The Kenyan sand boa (listed by CITES as Gongylophis colubrinus) is on CITES Appendix II 3. Choose captive-bred.
