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 7,200 cm² of floor (1,116 sq in) · 120 × 60 cm
Must be housed alone. Best housed singly; not social
- House one adult in an open-topped tortoise table or enclosure of at least 120x60 cm, larger outdoors, since glass tanks restrict airflow.
- Provide a basking spot of 32-35C under a heat lamp at one end and a cooler area of 20-24C, 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, dry substrate for burrowing, plus hides and basking rocks.
- A secure, predator-proof outdoor pen with sun and shade suits them in warm, dry weather.

- Shallow water dish and a soaking tub
- Flat feeding slate or tile to keep food off the substrate
Safe substrate: Topsoil and coco coir mix, deep enough to dig into · Orchid bark over soil
Care routine
Daily
- Check humidity for the species you keep
- Check temperatures and humidity
- Fresh water bowl
- Look the animal over
- Spot-clean waste and uneaten food
- Weeds and leafy greens
Weekly
- Time in a secure outdoor pen
- Warm shallow soak
Monthly
- Brief, infrequent handling onlyevery 2 weeks
- Check beak and nails

Diet
- 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
- 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.

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

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

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
Never (16)
AlcoholNo safe amount at any body weight on this site.
neverAnimal proteinCauses shell pyramiding and irreversible kidney damage. This includes dog and cat food, which is still sometimes recommended.
neverAvocadoPersin, concentrated in the skin, stone and leaves. Implicated in cardiac damage across birds, rodents and reptiles.
neverButtercupProtoanemonin.
neverCaffeineCoffee, tea and energy drinks. Cardiac and neurological toxicity at tiny doses for an animal this size.
neverChocolateTheobromine and caffeine. Small mammals and reptiles cannot clear either.
neverDaffodilToxic. Common in gardens where tortoises graze in spring.
neverFoxgloveCardiac glycosides.
neverFruitFor 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.
neverGarlicSame allium toxicity as onion, and more concentrated by weight.
neverIceberg lettuceNo nutritional value.
neverIvyToxic, and it grows exactly where a tortoise pen tends to be.
neverLeekAllium family. Same mechanism as onion and garlic.
neverOnionOrganosulphur compounds damage red blood cells. The whole allium family is out.
neverRhubarbOxalates.
neverSalty or seasoned human foodSalt, oil and seasoning. Crisps, chips, seasoned leftovers and processed meat are all out.
neverRare treats (3)
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 treatSpinachOxalates, in a species already at risk of bladder stones. Rarely if at all.
rare treatTomatoSugary and acidic. Never the leaves or stems. A small piece rarely, for species that take fruit at all.
rare treatOccasional (4)
Bell pepperSafe in small amounts. A little, once or twice a week.
occasionalButternut squashWell tolerated. A small amount weekly.
occasionalCucumberMostly water. Useful for a tortoise that will not drink. A slice occasionally.
occasionalKaleGood, but rotate it rather than feeding it daily. Twice a week.
occasionalEveryday foods (3)
Grasses and hayEssential for grazing species such as sulcatas and leopard tortoises. Available at all times for grazing species.
everyday foodLeafy greensCollard, mustard, turnip greens, watercress and rocket in rotation. Daily where weeds are unavailable.
everyday foodWeeds 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.
everyday foodThat 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.
What it really costs
Setup, monthly, first year and across a whole life, itemised and with the electricity worked out from the actual wattage. Published figures for the same animal disagree by a factor of four, so the calculator shows ranges rather than picking one.
Bedding and substrate
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.
safeOrchid bark over soilCommon for humid-species tables.
safeWith a caveat
Sand and soil mixesFine for arid species, but keep the sand fraction low enough that it still packs.
with a caveatNever
Pure sandEaten during grazing, and it does not hold a burrow.
neverWood shavings of any softwoodPhenols, and they are eaten.
neverRabbit pellets as a substrateSold for it. It moulds, and the tortoise eats a diet it was never meant to have.
