Sulcata Tortoise

Sulcata tortoises, also known as African spurred tortoises, are the third largest tortoise species in the world and the largest mainland tortoise in Africa. Adults regularly reach 24 to 30 inches in length and 80 to 150 pounds, with some individuals exceeding 200 pounds. They are hardy, personable, and impressive animals — but they are a serious commitment. Sulcatas can live 70 to 100 years, meaning they will likely outlive their owners. They require outdoor space as adults and cannot be permanently kept indoors. This is not an impulse buy.

Sulcata tortoises are grazers. Their diet should consist primarily of grasses (Bermuda grass, orchard grass, meadow hay) and weeds (dandelion, clover, plantain). Offer occasional dark leafy greens. Avoid fruits, high-protein foods, and high-oxalate plants. Calcium supplementation is essential. Access to a natural outdoor grazing area in warm climates is ideal and significantly reduces feeding costs. Overfeeding leads to rapid, unhealthy growth and shell pyramiding.

Juveniles can be kept in large indoor enclosures, but sub-adults and adults need large outdoor pens — a minimum 100 square feet for juveniles growing up, significantly more for adults. They are powerful diggers and will tunnel under fencing (barriers must be buried 1 to 2 feet deep). They also will bulldoze through lightweight structures. In cold climates, a heated tortoise house is required for cold months.

Sulcatas thrive at temperatures of 80 to 95 degrees Fahrenheit during the day. They come from hot, arid climates and are not cold-tolerant — temperatures below 50 degrees can be dangerous. A heated indoor shelter should maintain at least 60 to 65 degrees on cold nights. Bright, natural sunlight is ideal — UVB lighting is required for indoor enclosures.

Sulcata tortoises become very familiar with their owners and many will actively approach for food. Juveniles are easy to handle. Adults are too large for casual handling but will walk alongside you, take food from your hand, and develop clear recognition of their keepers. They are surprisingly intelligent for reptiles.

Metabolic bone disease and shell pyramiding from inadequate diet, substrate humidity that is too low for juveniles, respiratory infections, and internal parasites are the primary concerns. Sulcatas also develop very serious bladder stones if not properly hydrated — regular soaking and access to water is important. Work with a reptile vet experienced in large tortoise species.
