Species Profile & Temperament

THE COMMITMENT WARNING: Do not buy a Sulcata tortoise on impulse. Within 5-10 years, they will outgrow an indoor enclosure and must be moved to a permanent outdoor yard. They are incredibly strong and will dig massive burrows (sometimes 10+ feet deep), destroying gardens and breaking through weak fences. You must have the property space, the climate (or heated outdoor sheds), and the commitment to care for an animal that will likely outlive you.

Notable Morphs & Locales

Tortoises are generally wild-type, but the Sulcata has one highly prized, captive-bred mutation:

• Ivory Sulcata: A leucistic mutation. These tortoises lack dark pigmentation on their shell and skin, resulting in a stunning, solid cream or pale yellow color with bright ruby or black eyes. Their care is identical to wild-types.

Housing & Enclosure

Enclosure Size

• Hatchlings & Juveniles: A large tortoise table, moving up to a much bigger indoor enclosure quickly. Ask our staff to help you choose a size.
• Adults: Must be housed outdoors in a large, secure yard. Bigger is better; ask our staff to help you plan it.

Enclosure Setup (Outdoor)

• Fencing: Fences must be extremely strong (solid wood or reinforced metal). The bottom of the fence must be sunk well underground, as Sulcatas are expert diggers and will easily tunnel under a standard fence.
• Heated Hide: If nights get cold where you live, they MUST have a heated outdoor shed or "tortoise house" they can retreat into.

Humidity & Pyramiding (CRITICAL FOR BABIES)

• The Pyramiding Problem: Pyramiding is a permanent, debilitating bone deformity where the shell grows upward into sharp cones instead of remaining smooth. Dry air or dehydration while young is a major cause, along with poor calcium or UVB and too much protein.
• Hatchling Humidity: Baby Sulcatas must be kept humid in a closed-chamber enclosure (not an open-topped table), and soaked in shallow, warm water often. Ask our staff for the humidity range and soaking schedule we use.
• Adult Humidity: Adults do fine in standard ambient outdoor humidity, provided they have a muddy wallow or deep burrow to retreat into during the heat of the day.

Temperature & Lighting (Indoors)

• Temperatures: Give them a hot basking spot and a warm ambient temperature, with a smaller drop at night. Ask our staff for the range we keep ours at, and check it with a thermometer.
• Lighting: A high-output UVB bulb (like a T5 12% or 14% Desert bulb) is absolutely critical for indoor tortoises to prevent Metabolic Bone Disease. Outdoors, the sun provides all necessary UVB.

Diet & Nutrition

The 80/20 Herbivore Rule

Sulcatas require a massive amount of fiber and very low protein. Feeding them dog food, high-protein tortoise pellets, or lots of fruit will destroy their kidneys and deform their shells.

• Grasses & Hay (most of the diet): The bulk of their diet should be Timothy Hay, Orchard Grass, Bermuda Grass, and pesticide-free yard grass.
• Edible Weeds & Greens (the rest): Dandelion greens, clover, hibiscus flowers/leaves, cactus pads (Opuntia), turnip greens, and collard greens.
• Fruits & Veggies: A rare treat at most. Their digestive tracts cannot process the sugar in fruits or carrots properly, leading to severe gastrointestinal issues.

Supplements

• Calcium: Dust their greens with a calcium powder and follow its label for how often. Ask our staff which calcium we recommend for a sulcata kept indoors.
• Cuttlebone: Leave a whole cuttlebone in the enclosure. They will chew on it when they need calcium, and it helps keep their powerful beak trimmed.

Health & Husbandry

Common Health Issues

1. Pyramiding / Metabolic Bone Disease — Symptoms: Lumpy, raised scutes on the shell, weak legs. / Cause: Lack of humidity (for babies), lack of calcium/UVB, or too much protein in the diet. / Treatment: The damage is permanent, but correcting husbandry stops it from worsening.
2. Respiratory Infection — Symptoms: Bubbles blowing from the nose, wheezing, lethargy. / Cause: Cold temperatures combined with wet conditions. / Next step: See a vet who sees reptiles right away.
3. Impaction — Symptoms: Lack of feces, lethargy, loss of appetite. / Cause: Eating sand, gravel, or unnatural bedding. / Prevention: Never house on calcium sand or pure sand.

How We Keep Them at Critter Cabana & Gresham Pet Supply

• Beating Dry Oregon Furnace Air (and Summer Heat Spikes): Across the Willamette Valley and Portland Metro, running the house furnace all winter drops indoor humidity to 25–35%, which quickly causes stuck sheds and dehydration in screen-top tanks. To hold steady humidity for Sulcata Tortoise, our crew uses a deep substrate bed (or our store-shelf 10-Part Bioactive Mix of ReptiSoil, Coco Fiber, Orchiata Bark, Sphagnum Moss, and Leaf Litter), a dedicated humid hide packed with damp sphagnum moss, and partial screen cover when needed.
• Thermostat & Linear UVB Standard: Every heating element in our Newberg and Gresham reptile rooms runs on a thermostat probe, with a warm side and a cool retreat set to the range we keep ours at, paired with species-appropriate lighting on a 12-hour day/night timer. In summer, if an upstairs room climbs above 82°F, a dimming thermostat automatically backs down the basking lamp so the cool side never overheats.

Common Questions (FAQ)

What size tank does an adult Sulcata Tortoise actually need?

Sulcatas outgrow indoor enclosures. Juveniles need a large indoor tortoise table, and adults must live outdoors in a big, secure yard with a heated shelter. Ask our staff to help you plan the space and for the temperature range we keep ours at.

How do I keep Sulcata Tortoise humidity up during dry Oregon winters?

Oregon winter furnace heat dries out thin bedding fast. Use a deep moisture-retaining substrate mix (such as Zoo Med ReptiSoil blended with coco fiber, Orchiata bark, and sphagnum moss), provide an enclosed humid hide, and cover 50–70% of an open screen top with HVAC foil tape or a PVC panel if ambient humidity drops too low.
