General Care Requirements

Tortoises include small Mediterranean species, tropical forest dwellers and large grazing species. This guide provides a practical example for Hermann’s tortoises (Testudo hermanni). Its diet, climate and seasonal guidance should not be applied unchanged to red-footed tortoises, sulcatas or other species.

Natural Habitat

Hermann’s tortoises inhabit Mediterranean landscapes in southern Europe, including scrubland, grassland and open woodland. Their surroundings contain sunlit feeding areas alongside shrubs, leaf litter and sheltered ground. Even in a dry landscape, retreats can offer cooler, more humid conditions than exposed surfaces.

Housing

Provide a spacious ground-level enclosure with room to walk, forage and move between different temperatures. An indoor footprint of approximately 180 × 120 cm is a practical starting recommendation for one smaller adult, with larger animals requiring more space. A substantial, secure outdoor enclosure with suitable shelter should form part of the long-term housing plan where the climate permits.

Use diggable soil, planted cover, sheltered sleeping areas and gently varied terrain. Position heavy objects securely so they cannot collapse when undermined. Outdoor housing needs protection against escape, predators, overheating and prolonged cold or wet weather.

Provide fresh water in a shallow dish that the tortoise can enter and leave easily. Young animals particularly need access to a sheltered, slightly moist retreat; an enclosure that is dry and dusty throughout is unsuitable.

Housing individually avoids persistent courtship and aggression. Mature females need access to a sufficiently deep, suitable nesting area, including when kept without a male.

Temperature, Humidity & Lighting

During the active season, provide a basking area around 35°C, with cooler areas approximately 20–25°C. A night-time reduction to approximately 18–22°C is suitable for routine indoor active-season care.

Check basking surfaces with an infrared thermometer and air temperatures with digital probes. Control heating thermostatically and prevent contact with hot equipment.

Provide bright daytime illumination and appropriate UVB exposure, together with shade and enclosed retreats. UVB provision depends on the lamp, distance and enclosure layout; sunlight through ordinary window glass does not provide suitable UVB.

Maintain a moisture gradient rather than trying to keep the entire enclosure at one humidity reading. Surface areas can dry while sheltered soil retains some moisture. Hibernation requires a separate, planned approach appropriate to the animal’s health and origin; it should not result from simply allowing the enclosure to become cold.

Feeding

Offer a varied selection of suitable leafy plants daily, including dandelion, plantain, sow thistle, chicory and appropriate edible flowers. Use correctly identified plants from pesticide-free sources.

The diet should be fibrous and predominantly leaf-based. Fruit, animal protein and calorie-dense treats are unsuitable staples. Provide calcium supplementation and adjust any additional vitamins to the diet and UVB provision rather than combining multiple fortified products indiscriminately.

Lifespan

Hermann’s tortoises can live for 50 years or considerably longer. Their housing and care may need to continue beyond the lifetime of their first keeper.

Common Health Challenges

• Metabolic bone disease: Inadequate calcium intake or vitamin D provision can weaken the skeleton and shell.
• Abnormal shell growth: Growth rate, nutrition, hydration and environmental conditions all warrant assessment when the shell develops pronounced raised scutes.
• Dehydration: Dry housing throughout, inadequate drinking opportunities and illness can compromise hydration.
• Respiratory disease: Nasal discharge, breathing difficulties or persistent inactivity require veterinary assessment.
• Reproductive problems: Difficulty laying eggs can occur, particularly without suitable nesting conditions or when underlying disease is present.
• Parasites: Weight loss, abnormal droppings or poor growth may warrant faecal testing and veterinary investigation.
