Overview

What is this animal?

  • The sulcata, or African spurred tortoise, is the largest mainland tortoise; only the giant tortoises of the Galápagos, and of Aldabra and the Seychelles, grow larger.
  • Sold as a small, cheap hatchling, it grows steadily into a powerful animal that commonly exceeds 99 lb and can live well past 70 years.
  • Its size and longevity make it one of the most frequently surrendered reptiles, as owners are overwhelmed by its space, heat and feeding needs.

  • It is not a beginner or indoor-only pet.
  • Only take one on with a realistic, lifelong plan for housing a very large tortoise.

Temperament

  • Sulcatas are bold, strong and surprisingly active, often described as having dog-like persistence.
  • They push, dig and bulldoze through their environment and will move or break poorly secured furniture and fencing.
Show 4 more
  • Many recognise their keeper and are food-motivated, but their power demands respect.
  • They are not social and are best kept singly.
  • Males are territorial and combative, ramming rivals and harassing other tortoises, and even large enclosures rarely prevent conflict.
  • Solitary housing in adequate space is the only responsible arrangement for this species.

A good fit for

  • Keepers with land and a heated outbuilding
  • Experienced reptile owners in warm climates
  • People committed to a 70+ year, large animal
  • Those who can afford ongoing space and heating costs

Common mistakes to avoid

  • Buying a hatchling without adult-space planning
  • Indoor or tank housing as it grows
  • Low humidity and rich diet causing pyramiding
  • Underestimating cold sensitivity and escape ability

Enclosure

Minimum size: not yet recorded

This animal outgrows indoor housing entirely. The guide states a heated shed plus secure outdoor space rather than a figure, because no enclosure size makes an adult sulcata an indoor animal.

Must be housed alone. Solitary; males fight and harass other tortoises

  • Adults require a large, secure outdoor area with grazing, sun and shade, plus a heated, insulated shed or building they can enter, as they cannot be kept in tanks or vivariums long-term.
  • From hatchling onward they need a basking spot of 95-99°F, a cooler retreat and a warm night-time floor; sustained cold or damp is dangerous.
  • UVB is essential indoors and supplied by natural sun outdoors.
Show 2 more
  • Sulcatas are powerful diggers and burrowers and will undermine fences and walls, so boundaries must be deep, solid and escape-proof.
  • Give young animals a humid microclimate (a humid hide over moist substrate) and do not let the whole enclosure become arid, because hatchlings reared in dry air pyramid more; adults do well in drier, well-ventilated quarters with a humid retreat.

Care in depth

Diet

Grazer (grasses, hay)
  • Sulcatas are grazing herbivores built for a very high-fibre, low-protein, low-sugar diet.
  • The bulk of their food should be grasses and grass hay, supplemented with weeds and leafy greens.
  • They graze continuously, so constant access to safe grass or hay is ideal.
  • Avoid fruit, high-sugar vegetables, excess pellets and all animal protein, which cause rapid pyramided growth, kidney disease and bladder stones in this fast-growing species.
  • Provide calcium and a cuttlebone, and always supply fresh water plus regular soaking for hatchlings to maintain hydration.

Health

Signs of good health, and the common problems
  • Healthy sulcatas grow steadily with a relatively smooth shell, clear eyes, a dry nose and strong limbs.
  • The defining captive problem is shell pyramiding, driven by low humidity, poor diet and excess protein, alongside metabolic bone disease, respiratory infection from cold or damp, and bladder stones from dehydration and rich diets.
  • Their size makes veterinary care, transport and routine handling challenging, so prevention through correct husbandry is critical.
  • Sulcatas do not brumate.
  • Any nasal discharge, lethargy, soft shell or appetite loss needs prompt attention from a reptile-experienced exotics vet.

4 warning signs and how fast to act, 1 of them right away

Tortoise problems build over months, so the signs to watch are shape and habit rather than sudden events.

Go now

Runny nose, bubbles, or noisy breathingGo now. Respiratory infections in tortoises become chronic quickly.
Now

Today

Not eating for more than a few days outside a planned brumationCall today. An unplanned fast in an active tortoise is not normal.
Today
Swollen eyelids, or eyes held shutBook today. Often an infection, including upper respiratory disease, or eye damage after a cold spell or hibernation. Vitamin A deficiency, common in aquatic turtles, is less usual in a tortoise eating a varied diet of greens and weeds. All need treating.
Today

Soon

A soft shell in a growing tortoise, or a pyramided, lumpy shellBook an appointment and review UVB, diet and humidity. Both are husbandry outcomes. A soft shell can firm up once UVB, calcium and diet are corrected, though any deformity it caused stays; pyramided growth is permanent, but new growth can come in smooth.
This week

This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it, and the time to find one is before you need one.

Bedding and substrate

2 safe, 1 with a caveat, 3 to avoid

Tortoise substrate has to hold a burrow and hold moisture, because dry-brooded tortoises pyramid.

Safe

Topsoil and coco coir mix, deep enough to dig intoHolds humidity at the shell without being wet at the surface.
safe
Topsoil or loam with a low sand fractionDeep enough to dig into, dry on the surface and slightly moist lower down. Keep the sand fraction low enough that it still packs and holds a burrow.
safe

With a caveat

Orchid bark over soilFor humid-species tables such as red-foots. Kept damp, it is too wet underfoot for Mediterranean species and sulcatas.
with a caveat

Never

Pure sandEaten during grazing, and it does not hold a burrow.
never
Wood shavings of any softwoodAromatic oils, and they are eaten.

Rabbit pellets as a substrateSold for it. It moulds, and the tortoise eats a diet it was never meant to have.

Can a Sulcata Tortoise eat that?

A tortoise is a grazer, not a fruit eater. For Mediterranean and arid species, fruit and protein are the two things that do lasting damage.

The full list: 26 foods

Never (17)

AlcoholNo safe amount at any body weight on this site.
never
Animal proteinCauses shell pyramiding and irreversible kidney damage. This includes dog and cat food, which is still sometimes recommended.
never
AvocadoPersin, concentrated in the leaves, skin and stone. It damages the heart in birds and in many mammals, rabbits and rodents among them; it has not been studied in reptiles, so treat it as unsafe for them too.
never
ButtercupProtoanemonin.
never
CaffeineCoffee, tea and energy drinks. Cardiac and neurological toxicity at tiny doses for an animal this size.
never
ChocolateTheobromine and caffeine. Small mammals and reptiles cannot clear either.
never
DaffodilToxic. Common in gardens where tortoises graze in spring.
never
FoxgloveCardiac glycosides.
never
FruitFor Mediterranean and arid species (Hermann's, Greek, Russian, sulcata, leopard), fruit sugars disrupt the gut flora and are associated with parasitic overgrowth and diarrhoea. Tropical species such as red-footed tortoises are the exception and do take fruit; check the species guide.
never
GarlicSame allium toxicity as onion, and more concentrated by weight.
never
Iceberg lettuceNo nutritional value.
never
IvyToxic, and it grows exactly where a tortoise pen tends to be.
never
LeekAllium family. Same mechanism as onion and garlic.
never
OnionOrganosulphur compounds damage red blood cells. The whole allium family is out.
never
RhubarbOxalates.
never
Salty or seasoned human foodSalt, oil and seasoning. Crisps, chips, seasoned leftovers and processed meat are all out.
never
TomatoA sugary, acidic fruit, so the fruit rule applies: leave it out for Mediterranean and arid tortoises. The leaves, stems and green fruit are toxic to all of them.
never

Rare treats (2)

Pellets and commercial tortoise foodMost are too high in protein and too low in fibre. Weeds and greens are better in every respect. Not needed if the diet is right.
rare treat
SpinachOxalates, in a species already at risk of bladder stones. Rarely if at all.
rare treat

Occasional (4)

Bell pepperSafe in small amounts. A little, once or twice a week.
occasional
Butternut squashWell tolerated. A small amount weekly.
occasional
CucumberMostly water. Useful for a tortoise that will not drink. A slice occasionally.
occasional
KaleGood, but rotate it rather than feeding it daily. Twice a week.
occasional

Everyday foods (3)

Grasses and hayEssential for grazing species such as sulcatas and leopard tortoises. Available at all times for grazing species.
everyday food
Leafy greensCollard, mustard, turnip greens, watercress and rocket in rotation. Daily where weeds are unavailable.
everyday food
Weeds and wild forageDandelion, plantain, clover, sow thistle, hawkbit. This is the natural diet and it is free. Pick well away from roads and sprayed ground. The bulk of the diet, daily, for Mediterranean and Central Asian species; for sulcatas, a supplement to grass and hay.
everyday food

That plant is not on our list. Tortoises graze indiscriminately and a great many garden plants are toxic, so identify it before it goes anywhere near the pen.

Check the species guide before applying the fruit rule: it is correct for Mediterranean and arid tortoises and wrong for tropical ones like the red-footed.
