Arid reptile · Fossorial boa

Know whether your Kenyan sand boa's care is actually on track.

Your sand boa spends most of its life buried, so it can't tell you the warm spot has drifted cool or that its weight is creeping up. baskr watches the pattern across your logs, temperature, humidity, weight, feeding and shedding, and shows you what needs attention before it becomes a problem.

Kenyan Sand Boa

Feeding a little often

Weight up 11% over four weigh-ins. Stretch the interval toward every 7–10 days.

Warm spot

32–35°C · 90–95°F

Cool side

24–26°C · 75–79°F

Humidity

30–40%

Ideal ranges for Gongylophis colubrinus, the same targets baskr scores your logs against.

Basking and warm figures are surface temperatures at the spot; cool and ambient are air. Measure with a probe or infrared thermometer at the animal's height.

Kenyan Sand Boa: a few things worth knowing

Sand boas are fossorial, they spend almost all their time buried, cruising just under the surface.
They ambush from below, lying hidden with only the eyes exposed until prey wanders within reach.
Their eyes sit high on a wedge-shaped head, perfect for watching the world from beneath the substrate.
They're small and stocky, females reach a solid arm's-length while males stay noticeably smaller.
With good husbandry a Kenyan sand boa commonly lives 15–20+ years.

When is your kenyan sand boa active?

Nocturnal

Active by night

Where kenyan sand boas come from

Semi-desert of East and Northeast Africa

Wild climate. Hot, dry semi-desert; a life spent buried.

Why the care is what it is. This is why it is kept dry with deep loose substrate to burrow and a ~35°C warm spot, and why staying buried is healthy.

What baskr watches for your kenyan sand boa

Logging is the input. The product is spotting when a single off reading becomes a pattern worth acting on.

Warm-spot temperature

32–35°C (90–95°F) at the warm end

A few degrees cool for a week and digestion, appetite and activity quietly drop.

Thermal gradient

A cool side of 24–26°C (75–79°F)

No real gradient across the substrate leaves a boa unable to regulate its temperature.

Humidity

30–40% for a desert species

Persistently damp substrate is a scale-rot and respiratory risk worth catching early.

Weight trend

Steady in adults, gradual gain in growing snakes

Sand boas fatten easily, a steady climb from over-feeding is an early red flag.

Feeding & sizing

An appropriately-sized rodent every 7–10 days

As ambush feeders they'll take almost anything offered, baskr helps you keep the interval honest.

Shed quality

Clean sheds in one piece

Stuck shed or retained eye caps usually point to humidity that's drifted too low.

How to set up a kenyan sand boa terrarium

Minimum size
60×45×20 cm (2×1.5 ft footprint) for an adult, floor space and depth beat height for a burrower, so bigger is always better.
Temperatures
Warm spot 32–35°C (90–95°F), cool side 24–26°C (75–79°F), night drop to ~22–24°C.
Substrate
A deep, dig-friendly base like aspen or a sand/topsoil mix, at least several inches deep so they can fully bury themselves, this is essential, not optional, for a fossorial species.
Hides & décor
Deep substrate is the main 'hide', but add a surface hide or two at the warm and cool ends for a sense of security.
Layout
Run a warm-to-cool gradient across the floor: warm spot and heat source at one end, cool end at the other, with substrate deep enough to disappear into everywhere.

Plants for a kenyan sand boa terrarium

Safe to include

  • Snake plant (Sansevieria)
  • Haworthia
  • Prickly pear pads (Opuntia, despined)
  • Aloe
  • Hardy grasses
  • Spider plant

Avoid

  • Ivy
  • Oleander
  • Elephant ear
  • Most bulb plants (daffodil, tulip)

A constant burrower will uproot anything planted directly in the substrate, so sturdy potted succulents or décor work best. A desert species doesn't need a jungle, skip anything you can't confirm is non-toxic.

What to feed a kenyan sand boa, and what to avoid

Staples

  • Appropriately-sized mice (thawed frozen)
  • Rodents no wider than the snake's thickest point

Occasional / treats

  • A rat pup for larger females
  • Scented feeds to tempt a reluctant eater

Never feed

  • Prey wider than the snake's girth
  • Live rodents (bite-injury risk)
  • Wild-caught rodents (parasites/toxins)
  • Over-frequent feeding (obesity risk)

Supplements. Whole rodent prey is nutritionally complete, so dusting isn't usually needed, an occasional light supplement only if advised by a vet.

Good to know. Feed a single rodent roughly as wide as the snake's thickest part every 7–10 days for adults, more often for growing snakes. Because they're eager ambush feeders, over-feeding and obesity are the common mistake, track the interval and weight.

The gear that matters for a kenyan sand boa

The right kind of kit, pick brands you trust.

Heat source

A regulated under-tank heater or overhead source at the warm end to hold ~32–35°C at substrate surface, belly heat suits a snake that lives buried.

Thermostat

Non-negotiable, it controls the heat source so a burrowing snake pressed against warm glass or substrate can't overheat or burn.

UVB lighting (optional)

A low-output T5 HO UVB tube (Ferguson zone 1) can benefit surface activity, though a mostly-buried species needs less than diurnal baskers. Replace every 12 months.

Thermometer + hygrometer

Digital, with a probe read at the substrate surface, not stick-on dials. Check both ends of the gradient.

Enclosure

A 2×1.5 ft (or larger) front-opening vivarium with a secure lid and deep substrate capacity for burrowing.

The kind of thing baskr will tell you

Grounded in your own logs and the ideal ranges above, plain language, never a diagnosis.

Warm spot read 28°C for 5 days, below the 32–35°C your sand boa needs to digest. Check the heat mat or thermostat.

Sand boa's weight is up 11% over four weigh-ins, feeds are landing too often, stretch the interval out.

Humidity has averaged 55% this week, high for a desert species. Let the substrate dry out before scale problems start.

Kenyan Sand Boa care questions

What temperature should a Kenyan sand boa's warm spot be?+

Aim for roughly 32–35°C (90–95°F) at the warm spot, with a cooler side around 24–26°C (75–79°F) so it can thermoregulate under the substrate. baskr checks the temperatures you log against this range and flags a sustained drift, but always verify with a good thermometer at substrate surface.

Why does my sand boa stay buried all the time?+

That's completely normal, Kenyan sand boas are fossorial ambush predators that spend most of their lives buried, surfacing mainly to feed or in the evening. Deep substrate isn't decoration, it's a core welfare need. baskr won't mistake normal hiding for a problem, but it will flag if feeding or weight patterns shift.

How often should I feed a Kenyan sand boa?+

Adults typically take one appropriately-sized rodent every 7–10 days, growing snakes more often. They're enthusiastic feeders, so over-feeding and obesity are the usual risk, keep prey about as wide as the snake's thickest point and let baskr track the interval and weight trend. Verify sizing against a current care sheet.

Is my sand boa overweight?+

Sand boas should look rounded but not bloated, with no rolls or a spine lost in fat. Because they'll eat eagerly whenever offered, weight can creep up quietly. baskr charts the trajectory so a slow climb stands out early; if you're unsure, an exotics vet can assess body condition, baskr is a husbandry assistant, not a diagnosis.
