Spring Awakening: Veterinary Advisory Issued as Tortoises Emerge from Hibernation
With the UK approaching the end of the traditional hibernation season, reptile veterinarians are urging tortoise keepers to remain vigilant for signs of Post-Hibernation Anorexia (PHA).
The transition from dormancy to activity is the most critical period in a tortoise’s annual cycle. Experts warn that waking a tortoise too quickly, or failing to rehydrate them adequately within the first 24 hours, can lead to renal complications.
The "Jackson Ratio" Reminder
Keepers of Mediterranean species (such as Hermann's and Spur-thighed tortoises) are advised to check their pet's weight immediately upon waking. Any animal that has lost more than 10% of its body weight during winter should be seen by a specialist vet immediately.
Dr. Sarah Miller, a reptile specialist, noted in a recent community bulletin: "We see a spike in emergency admissions every March. The most common mistake is assuming a tortoise will eat immediately. They need heat and hydration first to flush out toxins accumulated during sleep."
Key Safety Checks for March 2025
- Hydration: Bathe the tortoise in tepid water twice daily for the first week.
- Heat Lamps: Ensure UV bulbs are less than 12 months old; degraded bulbs do not provide the Vitamin D3 required for calcium absorption.
- Feeding: Do not be alarmed if they refuse food for 48 hours, but activity levels should return to normal quickly.
