Russian Tortoise — Breed Feeding & Safety Guide
The Russian tortoise (Testudo horsfieldii) is one of the most commonly kept tortoise species in the UK and is often recommended for first-time tortoise keepers due to its relative hardiness and manageable size. They are active, curious animals with distinct personalities that become recognisably tame with regular, gentle handling. Russian tortoises are natural hibernators and will hibernate in winter if temperature and day length conditions trigger this behaviour — correct hibernation management is essential for their health. Russian tortoises are strictly herbivorous and their diet in captivity should replicate the fibrous, low-protein, low-sugar weeds and grasses they eat in the wild. The majority of their diet (80–90%) should consist of dark leafy weeds and grasses: dandelion leaves and flowers, plantain (the weed, not the fruit), clover, hibiscus leaves, wild garlic mustard (hedge garlic), sow thistle, and sedum. Commercial tortoise food can supplement but not replace fresh vegetation. Fruits are high in sugar and inappropriate for Russian tortoises — avoid bananas, grapes, strawberries, and citrus. Calcium supplementation (finely ground cuttlebone or calcium carbonate) should be dusted on food two to three times weekly.

Foods to avoid
All fruit (too high in sugar for a steppe-adapted herbivore — can cause gut flora imbalance). Spinach, kale, broccoli in quantity (high oxalates and goitrogens — occasional small amounts only). Lettuce (iceberg especially — essentially water with no nutritional value). Cucumber and courgette in large amounts (very low nutritional density). Meat, insects, or any animal protein (inappropriate for this obligate herbivore). Dog or cat food (completely inappropriate). Rhubarb (highly toxic — oxalic acid).
Common health considerations
Respiratory infections (runny nose syndrome) are common in Russian tortoises kept in incorrect humidity or temperature conditions. Metabolic bone disease (MBD) can develop from insufficient calcium, phosphorus imbalance, or inadequate UV-B lighting (needed for vitamin D3 synthesis). Bladder stones can develop from high-protein diets. Correct UV-B provision (high-output UV-B lamp or outdoor access in summer) is essential — without it, tortoises cannot properly metabolise calcium regardless of dietary intake. Hibernation management is critical: incorrect hibernation temperatures can cause respiratory infection or death.
