Russian Tortoise

Is a Russian tortoise right for you?

The Russian tortoise (Testudo horsfieldii, also called the Central Asian tortoise) is one of the most widely kept small land tortoises thanks to its compact size and hardiness. It is not a "sits in a box and eats lettuce" pet, though: it is very active, digs constantly, tries to escape, and can outlive its owner.

Before you adopt

Legal status. All land tortoises (family Testudinidae) are listed on CITES Appendix II, meaning international trade requires a permit. Check your country's import and sale rules before buying, and ask the seller for the animal's origin and paperwork; an animal without documentation is both a legal risk and a way of supporting smuggling. In Turkey, for example, the Russian tortoise is not native and must have entered the country legally with CITES paperwork, while the country's own native tortoise (Testudo graeca) may not legally be collected from the wild, sold, or exported at all.

Don't confuse it with a native tortoise. In many countries, native tortoise species are protected and collecting them from the wild is illegal. Make sure an animal sold as a "Russian tortoise" at a market, roadside, or online is not actually a wild-caught native species passed off under a different name. If you find a wild tortoise crossing a road near your home, do not take it home as a pet; move it a short, safe distance in the direction it was already heading, away from traffic, and leave it there.

Wild-caught individuals. The trade still includes wild-caught Russian tortoises. These individuals show higher rates of parasites, herpesvirus, and upper respiratory infection. Choose a captive-bred hatchling where possible, and have a new tortoise checked by a vet within the first week.

Size and lifespan. Adults typically reach a 13-25 cm (5-10 in) shell length and 300-1,500 g in weight, with females larger than males. With good care, a lifespan well beyond 40 years is expected.

Enclosure set-up

Outdoor pen (preferred)

• At least about 120x120 cm for a single adult; double the area for a second animal.
• Walls at least 30 cm high, with the top edge angled inward.
• A fence or barrier buried around 20 cm deep to stop escape by digging; deeper still in soft soil.
• Covered with wire mesh on top against cats, dogs, birds, and rodents; include shade and a sheltered hide box.

Indoor set-up

• An open-topped tortoise table of roughly 180x60 cm for an adult. A glass aquarium traps stale air and the tortoise will constantly scratch at the glass because it cannot understand what it is.
• Substrate: a roughly 50/50 soil and sand mix (or coconut fiber), at least 5 cm deep; a deeper corner helps since this species loves to dig. Newspaper, pellets, and alfalfa hay are not suitable.

Sources vary by a few degrees on these figures; what matters is that the tortoise can choose between a warm and a cool area. Digestion stops in the cold.

UVB: A strong UVB lamp (or a mercury vapor bulb that emits UVB), on for 8-12 hours a day. Replace it on the manufacturer's schedule (typically every 6-12 months). Direct summer sunlight is the best UVB source, but UVB does not pass through glass.

Humidity: Wild burrows are humid, but a dry indoor substrate is generally preferred; high humidity combined with a wet substrate and low temperature raises the risk of respiratory disease.

Water: A shallow, tip-proof water dish. Hatchlings can be soaked in lukewarm water for 15-20 minutes once a week.

Feeding

The Russian tortoise is a grazer that feeds on broad-leaved wild plants in the wild.

Core diet: Dandelion, plantain, clover leaf, endive, arugula, and dark leafy greens such as curly kale and collards. Pesticide-free garden weeds are ideal; do not pick from roadsides.

Frequency: Hatchlings daily; adults can have extra greens a few times a week on top of daily grazing. Overfeeding causes rapid growth and shell pyramiding.

Do not feed: Fruit (upsets digestion), meat, cat or dog food, bread, legumes, and high-protein foods. Iceberg lettuce has little nutritional value.

Supplements: Dust greens with calcium powder without D3; add a D3 supplement indoors on your vet's advice. Calcium works together with UVB for shell health.

Health and lifespan

VCA recommends an annual vet check and a fecal parasite check at every visit.

Common problems:

• Respiratory infection: Nasal discharge or bubbles, wheezing, loss of appetite, lethargy. Cold, damp conditions and stress set the stage; herpesvirus is also a cause. See a vet.
• Internal parasites: Often symptomless; in severe cases, diarrhea and weight loss.
• Pyramiding: Shell scutes rising like towers. Linked to excess protein, overfeeding, low humidity, and dehydration; permanent once it happens, so prevention matters.
• Metabolic bone disease: A soft or misshapen shell, deformed legs. Caused by insufficient UVB and calcium.
• Bladder stones: Caused by dehydration and unbalanced diet; signs include hind-leg weakness and changes in droppings or urates. Seen on X-ray, and they make brumation dangerous.
• Shell infection and mouth rot: Pitting, sores, or odor on the shell; redness and cheesy deposits in the mouth.
• Loss of appetite after brumation: A tortoise that does not eat after waking should be seen by a vet.

Brumation (winter dormancy) In the wild, the Russian tortoise spends most of the year underground; in captivity, a short, controlled brumation is recommended. Done incorrectly, it can be fatal.

1. Vet check: A health and parasite check a few weeks before brumation. Sick, underweight, bladder-stone, or very young individuals should not be brumated.
2. Fasting: Food is gradually reduced and then withheld entirely for the last two weeks before brumation, while water and warm soaks continue, so the gut can empty.
3. Temperature: 4-7 °C is generally considered ideal; below 3 °C risks freezing, above 10 °C the tortoise burns energy and may wake early. A thermometer-monitored refrigerator used only for this purpose is the safest method. A heated apartment is too warm, and an unheated balcony in winter can freeze.
4. Duration: Generally should not exceed 8-12 weeks.
5. Weighing: Weigh before and periodically during brumation (waking the tortoise every few weeks to check). Around 1% of body weight lost per month is considered normal; noticeably more should end the brumation and prompt a vet visit.
6. Waking up: Warm gradually, offer a warm soak, then water and food. See a vet if the tortoise does not drink or does not eat within a few days.

Salmonella: Wash your hands after every contact and cleaning.

Handling and behavior

1. Support from below, on both sides of the shell. Legs dangling in open air can cause panic.
2. Never let it fall from a height. A cracked shell is a serious injury.
3. Keep handling brief. Tortoises do not enjoy being petted; trust is built through hand-feeding.

Reading the behavior:

• Constant digging: Normal; it seeks to cool off in heat and shelter in cold. More digging in autumn can signal brumation preparation.
• Pacing along a wall: The space may be too small or the temperature wrong.
• A male chasing a female and ramming her shell: Courtship behavior, but it wears the female down; two males may fight each other.

History and life in the wild

The Russian tortoise lives across the Central Asian steppes, spanning Kazakhstan, Uzbekistan, Turkmenistan, Afghanistan, and Iran. It has a short active period between hot summers and harsh winters, and can spend most of the year dormant in burrows it digs itself.

For many years it was collected from the wild in large numbers for the pet trade. It is assessed as vulnerable (VU) on the IUCN Red List, which is why its trade is monitored under CITES. Choosing a captive-bred individual is the most concrete contribution a keeper can make to the species' future in the wild.
