Owners of tortoises, particularly older animals such as those of Greek origin, are advised to seek professional veterinary guidance when considering hibernation. Proper care before, during, and after hibernation is essential to ensure the health and safety of these reptiles.

Veterinary experts recommend that any tortoise intended for hibernation undergo a thorough health assessment to confirm it is fit for the process and has accumulated sufficient energy reserves over the active summer months. Identification of the species is also critical, as not all tortoises are suitable candidates for hibernation.

During hibernation, maintaining a stable ambient temperature between 3 and 7 degrees Celsius is crucial. Regular monitoring of the tortoise’s weight is advised, as it is normal for these animals to lose approximately 1 percent of their body weight each month while hibernating. However, any increase in temperature causing the tortoise to become active can result in accelerated weight loss and depletion of vital energy reserves. Temperatures below freezing pose risks such as corneal damage and, potentially, death.

The recommended duration of hibernation typically ranges from eight to twelve weeks, though this may vary depending on veterinary advice and the individual tortoise’s condition. Following hibernation, a follow-up health check is necessary to assess recovery, and owners should be prepared to provide artificial UVB lighting and heat to support the tortoise’s return to normal activity.

Comprehensive resources on tortoise hibernation and care are available through organizations such as the Royal Veterinary College, the Tortoise Protection Group, and the Tortoise Trust, which provide detailed guidance on preparation, monitoring, and post-hibernation care.

Veterinarians with extensive experience in reptile care emphasize the importance of professional consultation to ensure the well-being of tortoises undergoing hibernation, particularly those that are elderly or whose hibernation history is uncertain.
