Sulcata Tortoise

Overview

Sulcata tortoises (Centrochelys sulcata) are the third-largest tortoise species and the largest mainland tortoise. Adults reach 24-30 inches in shell length, regularly exceed 100 pounds, and live 70-100+ years. Buying a sulcata is a multi-generational commitment; many end up in rescues when keepers underestimate adult size and lifespan.

Enclosure

Hatchlings can be kept indoors temporarily, but adults require a large outdoor enclosure with secure fencing buried at least 18 inches underground (they dig). A minimum of a few hundred square feet of grazing space is needed, with thousands of square feet preferred. A heated, insulated shelter is required wherever winter temperatures drop. Substrate should be packed soil, grass, and natural ground; avoid sand.

Temperature and humidity

Sulcatas thrive at daytime temperatures of 80-95F with a basking spot around 100F. Nighttime should not drop below 60-65F; provide a heated indoor shelter for cold nights. Humidity should be moderate for adults (40-55%) but hatchlings require higher humidity (60-80%) and regular soaking to prevent pyramiding. Strong UVB is essential.

Diet

Sulcatas are strict grazers. Feed a diet of grasses, hay (orchard, timothy, bermuda), weeds (dandelion, plantain, mallow), and dark leafy greens. Avoid fruit, lettuce, and high-protein foods, which cause shell deformity and kidney damage. Provide a cuttlebone or calcium block for free-choice calcium.

Handling and temperament

Sulcatas are generally docile but are not pets that enjoy handling. They will tolerate brief interaction but are too heavy to lift safely once adult. They can be surprisingly fast and strong; secure enclosure walls are essential.

Common health issues

The most common problems are pyramiding from low-humidity rearing and improper diet, shell rot, respiratory infections, and impaction. Long-lived tortoises also accumulate kidney issues from chronic dehydration or high-protein diets. Annual vet exams with an exotics specialist are recommended.
