How Often to Feed a Russian Tortoise (and How Much)

Young Russian tortoises eat daily; adults get a shell-sized pile of greens a day. How much to give, what to feed every day, and how not to overfeed.

· 7 min read

How often to feed a Russian tortoise depends on its age. Young, growing Russian tortoises are fed every day. Adults are fed every day too, but in a limited amount: roughly a pile of leafy greens and weeds about the size of their shell. The bigger risk for a pet Russian tortoise isn’t going hungry, it’s eating too much.

The daily schedule and portion sizes come from ReptiFiles’ Russian tortoise care sheet. The Merck Veterinary Manual agrees that small tortoises should be fed more often than larger ones. The food and water rows come from the Royal Veterinary College (RVC), whose Mediterranean tortoise care sheet covers Horsfield’s tortoises, the UK name for the same species.

How often should a baby Russian tortoise eat?

Every day. ReptiFiles says young, growing Russian tortoises can have as much as they’ll eat each day, because they’re putting on shell and bone.

“As much as they’ll eat” still means the right food. Growth that’s too fast is its own problem: Merck’s tortoise nutrition chapter links rapid growth on high-protein diets to shell deformities, and advises weighing young tortoises regularly to keep growth steady, neither too slow nor too fast. So give a young tortoise plenty of weeds and leafy greens, and keep protein-rich and sugary foods out of the bowl.

How often should an adult Russian tortoise eat?

Once a Russian tortoise is close to adult size, ReptiFiles recommends switching to a limited daily portion to prevent obesity. In practice, that’s one meal a day of about a shell-sized pile of greens.

It helps to know how little these tortoises eat in the wild. The San Diego Turtle & Tortoise Society (SDTTS) notes that wild Russian tortoises are active for only about three months a year, typically March to May. The Tortoise Trust puts it at a maximum of about 90 days of feeding a year, with the tortoise eating as much as it can during that short window to carry it through long dormant periods. A pet tortoise offered food every day of the year has a very different life, and the Tortoise Trust sees that as the main feeding problem in captivity.

That doesn’t mean you should starve your tortoise to copy the wild. It means a measured portion works better than a bowl that’s always full, and a healthy adult that skips a meal now and then is nothing to worry about.

How much should you feed a Russian tortoise?

TortoisePortion
Hatchling or juvenileAs much as it eats at one daily meal
AdultA pile about the size of its shell, once a day

Treat these as starting points and adjust to your tortoise’s appetite and weight.

  • Serve food on a plate or tray. ReptiFiles and the RVC both warn against feeding straight on the substrate, which your tortoise can swallow along with its greens.
  • Remove leftovers so you can see how much your tortoise actually ate.

Can you overfeed a Russian tortoise?

Yes, and it’s one of the most common mistakes. The SDTTS care sheet notes that Russian tortoises tend to be overweight in captivity. The Tortoise Trust warns that even good food can cause trouble in excess, from growing too fast to carrying too much fat.

Signs you may be giving too much:

  • Chubby legs. The SDTTS suggests watching for fat bulging when your tortoise pulls its legs into its shell. If it looks chubby, cut back a little on the amount.
  • Leftovers every day. If a shell-sized pile is never finished, the portion is too big.
  • Very fast growth in a young tortoise, compared with earlier monthly weights.

Weighing your tortoise once a month on a kitchen scale, and writing it down, is the easiest way to see a trend. If you use ShellPal, the monthly check-in keeps your tortoise’s weight on a growth chart so you can spot a jump early. If you think your tortoise needs to lose weight, ask a reptile vet to help you plan it rather than cutting food sharply on your own.

What can Russian tortoises eat every day?

The goal is high fiber, low protein and low sugar, which is what wild Russian tortoises eat. The RVC recommends that weeds make up more than 70% of the diet, with vegetables and salad used when weeds aren’t available.

Everyday staples (sources: RVC, ReptiFiles, SDTTS):

  • Weeds: dandelion leaves and flowers, plantain, clover, sow thistle, mallow, chickweed
  • Grasses: Bermuda, timothy, rye, fescue and bluegrass, untreated
  • Store-bought greens: endive, escarole, chicory, romaine and watercress
  • Edible plants and flowers: hibiscus, nasturtium, honeysuckle, Opuntia cactus pads, grape leaves (not grape ivy) and sedum

Pick weeds and flowers only from places that haven’t been sprayed with pesticides or fertilizer. If you’re not sure whether a plant is safe, The Tortoise Table (thetortoisetable.org.uk), recommended by both the RVC and ReptiFiles, keeps a searchable plant database.

Feed only now and then, in small amounts (ReptiFiles): spinach, kale, cabbage, chard, collards, broccoli and beet greens.

Do Russian tortoises need fruit?

No. The RVC says to avoid fruit because of its sugar content, and the Tortoise Trust recommends no fruit at all for this species, noting that it can upset digestion. ReptiFiles allows fruit only as a very rare treat. Flowers make a better treat.

What should Russian tortoises never eat?

  • Meat, eggs and other animal protein. The SDTTS is blunt that these tortoises don’t eat animal protein. ReptiFiles allows feeder insects only as a very rare treat, and you can leave them out entirely.
  • Cat or dog food. The Tortoise Trust links it to serious kidney and bladder problems in Horsfield’s tortoises.
  • Bread, cheese, milk and other human food. None of it belongs in a tortoise’s diet.
  • Lettuce and fruit as the main diet. The Tortoise Trust warns that supermarket produce often has too little fiber and too much sugar, and describes a lettuce-and-fruit diet as a poor one.

Calcium and vitamins

Russian tortoises need a calcium-rich diet. The sources describe a few ways to provide it:

  • Calcium powder: the SDTTS suggests a light sprinkle of calcium carbonate on food.
  • Alternating supplements: the RVC recommends alternating a calcium powder with a vitamin and mineral powder, especially when the diet relies on supermarket greens.
  • Cuttlebone: ReptiFiles suggests leaving a cuttlebone in the enclosure as a calcium source your tortoise can nibble, which also helps keep its beak trim.

Follow the product label for how often to use a powder, and ask a reptile vet if you’re unsure what your tortoise needs. Calcium only works alongside good UVB lighting, so check your light schedule too.

Water

Food is only half the routine. The RVC says water should always be available and changed daily, and the SDTTS recommends a shallow dish sunk into the substrate that your tortoise can walk in and out of. Russian tortoises can drown in deep water, so keep it no higher than the bottom edge of the shell. A regular soak helps too; see how often to soak a tortoise for the schedule.

Does a Russian tortoise eat less at certain times of year?

Yes, and that’s normal. The British Chelonia Group notes that Horsfield’s tortoises hibernate in winter and may aestivate (rest through the heat) in the hottest summer weather. The SDTTS describes food intake tapering off as the weather cools. In one Tortoise Trust keeper’s account, their tortoise’s appetite peaked in May to July and fell almost to nothing by early October.

Appetite also depends on warmth and light. A tortoise that’s too cool won’t feel like eating. The RVC recommends a basking spot of about 95°F (35°C) and a cooler end of about 68–77°F (20–25°C), with lights on for around 12 hours a day.

If you plan to hibernate your tortoise, winding down its food beforehand is part of that plan, and a pre-hibernation vet check is the place to start.

When to see a reptile vet

Feeding less in autumn is expected. Book a visit with a reptile vet if:

  • Your tortoise hasn’t started eating within a week of waking from hibernation, even with good warmth and light (the SDTTS threshold).
  • It stops eating outside its usual seasonal slowdown, and its temperatures, lighting and water are all right.
  • You notice discharge from the eyes or nose, or it seems unusually weak.
  • Its weight drops or climbs quickly between monthly weigh-ins and you can’t see why.

The RVC also recommends a yearly health check for pet tortoises, which is a good time to review your tortoise’s portions and diet with the vet.
