Overview

What is this animal?

  • The Russian tortoise comes from the arid steppes of Central Asia and is one of the smaller, more cold-tolerant tortoises kept as a pet.
  • It is active and an enthusiastic digger and climber, which makes it engaging but also a frequent escape artist.
  • Despite its modest size, it is a multi-decade commitment that often lives past 40 years and may pass between owners.
  • Many are sold as easy starter pets, yet they need correct lighting, space and a fibrous, weed-based diet to avoid the chronic problems common in captive tortoises.

Temperament

  • Russian tortoises are bold and determined, spending much of the day foraging, basking and trying to dig under or climb over barriers.
  • They tolerate gentle, infrequent handling but, like all tortoises, do not enjoy being picked up and are not cuddly pets.

  • They are not social and are best kept singly.
  • Males can be aggressive, ramming and biting, and will harass females.
  • Housing two together often leads to stress, injury and competition over food and basking spots, so solo housing is the responsible default.

A good fit for

  • Keepers wanting a smaller tortoise species
  • People who can provide an outdoor pen in summer
  • Owners ready for a 40+ year commitment
  • Those wanting an active, foraging reptile

Common mistakes to avoid

  • Cramped glass tanks instead of an open table
  • Feeding fruit or high-protein foods
  • Skimping on UVB, causing shell deformity
  • Brumating a sick or underweight animal

Enclosure

Minimum 24 sq ft of floor · 7 x 3.5 ft

Usually kept alone. Best housed singly; not social

  • Indoors, house one adult in an open-topped tortoise table or pen of at least 7 x 3.5 ft, and larger if you can, since glass tanks restrict airflow.
  • Provide a basking spot of 90-95°F under a heat lamp at one end and a cooler area of 68-75°F, with night temperatures allowed to drop.
  • A UVB source covering the basking zone is essential for vitamin D3 and shell health; replace tubes on the manufacturer's schedule.

  • Give a deep, well-drained substrate for burrowing that is dry on the surface but slightly moist lower down (mist it lightly in the morning), plus a humid hide, other hides and basking rocks.
  • The best home, though, is a secure, predator-proof outdoor pen of at least 108 sq ft with sun, shade and a dry, heated shelter, used whenever the weather is warm and dry; the indoor table is for cold or wet spells.

Care in depth

Diet

Herbivore (weeds, leafy greens)
  • Russian tortoises are herbivores adapted to coarse, high-fibre, low-protein plants.
  • Feed a varied mix of weeds and leafy greens such as dandelion, clover, plantain, sow thistle, endive and spring greens.
  • Avoid fruit, which can cause gut upset, and never feed dog food, grains or meat.
  • Dust food with calcium regularly and provide a cuttlebone.
  • Always offer fresh water and bathe young tortoises a few times weekly to support hydration.
  • Low-fibre, high-protein or high-sugar feeding causes pyramided shell growth, kidney strain and obesity.

Health

Signs of good health, and the common problems
  • A healthy tortoise has clear eyes and nostrils, a smooth firm shell, a good appetite and strong leg power when lifted.
  • Watch for a runny nose, wheezing or open-mouth breathing, which signal respiratory infection, and for a soft or pyramided shell from poor UVB, calcium or diet.
  • Common problems include metabolic bone disease, shell pyramiding, bladder stones, parasites and overgrown beaks.
  • Healthy adults may brumate in cool months, but only if fit and parasite-free; never brumate a sick or underweight tortoise.
  • Use an exotics vet for faecal checks and any concern.

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

Is your enclosure big enough?

These are the smallest sizes that give good conditions, not legal minimums. More room is always better.

Every figure, and where it comes from

This is the indoor figure. The best home is a secure outdoor pen of at least 108 sq ft, used whenever the weather is warm and dry, with this table or a heated shelter for cold and wet days.

The recognised standards do not agree on this one
ReptiFiles: 7 x 3.5 ft for one adult, preferably larger, sized for a tortoise of up to about 10 in. The figure this site uses, which ReptiFiles gives as its minimum recommended size. It also says it is ideal to house a Russian tortoise outdoors whenever possible. Checked 2026-10-23.
Tortoise Trust: An indoor pen of about 6 x 6 ft minimum for one adult, with a secure outdoor pen as the main home. A larger indoor figure. The Trust advises against keeping any tortoise indoors all the time. Checked 2026-10-23.
RSPCA (UK): At least 6 x 4 ft indoors for one tortoise, plus an outdoor enclosure of 108 sq ft. Indoor and outdoor space together, for one tortoise. A little less indoor floor than the figure used here. Checked 2026-10-23.
Swiss Animal Protection STS: At least 108 sq ft of outdoor enclosure for two to four tortoises. It says only outdoor housing meets these tortoises' needs, and a terrarium does not. Checked 2026-10-23.
Swiss legal minimum (Tierschutzverordnung, Anhang 2, Tabelle 5): 8 x 4 shell lengths for one or two tortoises, and 2 x 2 shell lengths more for each extra, plus an outdoor run whenever the weather allows. A legal minimum, recorded for context: 5 x 2.5 ft for an 8-inch shell. The figure used here meets it for a shell of up to about 10 in. Checked 2026-10-23.
Austrian legal minimum (2. Tierhaltungsverordnung, Anlage 3): 22 sq ft (for example 6.5 x 3.3 ft) for one or two animals over 4.5 in, and 5.5 sq ft more for each extra. A legal minimum, recorded for context. Juveniles of 2.4-4.7 in already need 11 sq ft. Checked 2026-10-23.

Can a Russian 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.

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.

Everyday foods (3)

Grasses and hayEssential for grazing species such as sulcatas and leopard tortoises. Available at all times for grazing species.

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.
