This is a specific conversation about Reptile setup — getting the environment right — ask about yours and get one honest answer for your exact situation.

Reptile welfare is almost entirely determined by getting the environment right — temperature gradient, UV lighting, humidity, and substrate all need to match the specific species' natural habitat. Getting this wrong causes chronic stress and illness, and for a fossorial desert snake like a Kenyan sand boa, substrate in particular is non-negotiable. What's the age of your animal, and are you setting up a new enclosure from scratch or looking to improve what you already have?
She's about four years old, fully adult. I've had her for two years on a mix of play sand and topsoil but I'm not convinced it's right — it clumps when wet and I'm worried about humidity creeping up. Starting fresh basically.

Good instinct to revisit it. Play sand and topsoil blends tend to retain moisture in a way that really doesn't suit Kenyan sand boas — they're from the arid scrublands of East Africa and need dry, loose substrate they can burrow through freely. Humidity sitting too high for too long predisposes them to respiratory issues and scale rot. For a full reset, what size enclosure are you working with, and do you currently have hides she actually uses, or is she spending most of her time buried?
It's a 3ft wooden viv. She buries herself constantly — I rarely see her. She does have two hides but honestly I think she just ignores them and prefers to be under the substrate.

That's completely normal behaviour for the species — they're obligate burrowers and a good deep substrate layer is their primary refuge. The hides matter less than you'd think for sand boas compared to most other snakes, though a warm-side hide flush to the glass still helps on the thermoregulation side. For substrate, I'd go with Arcadia EarthMix Arid. It's a professionally formulated mix designed specifically for arid and semi-arid species — it's loose and free-flowing when dry, holds a burrow tunnel without collapsing, and critically it doesn't compact or retain moisture the way sand-soil blends do. It's also dust-reduced, which matters for a burrowing snake that's pushing her snout through it constantly. For a 3ft viv, aim for at least 4–5 inches depth so she has genuine burrowing room. Fill one end slightly deeper if you want to give her a thermal gradient within the substrate itself.
That sounds much better. Should I ditch the hides entirely then, or keep one in?
inparticular.ai
Keep one — place it on the warm side, directly over your heat mat or above your heat cable zone. Even though she'll mostly be under the substrate, having a hide there means she can thermoregulate at the surface level without feeling exposed. A low-profile, tight-fitting hide works best for sand boas because they like to feel enclosed on all sides. The Exo Terra Snake Cave is a solid choice — it's weighted so it won't shift when she pushes against it from underneath, the opening is small enough to feel secure, and the flat base sits flush to the substrate surface. One on the warm side is enough for her setup.
Perfect. And I just keep the substrate completely dry — no misting at all?
inparticular.ai
Correct — no ambient misting. The only moisture management you need is a small damp hide during shed cycles, which you can create by putting slightly moistened sphagnum moss inside a sealed hide with a small entrance hole. You offer it when you notice her eyes go blue or her colour dulls, then remove it once she's shed. Outside of that, the main enclosure stays dry. Ambient humidity for Kenyan sand boas should sit between 30–40% — if you're in a humid climate and struggling to keep it down, ensure your viv has adequate cross-ventilation on both sides.
