As days get shorter and cooler, many tortoises and some other reptiles naturally slow down for brumation, a winter dormancy period similar to hibernation. Done correctly it can be healthy, but done in a sick or underweight animal, it can be dangerous.
Start with a Pre-Brumation Exam
Only healthy reptiles should brumate. An exam several weeks beforehand lets us check weight and body condition, look for signs of infection or parasites, and recommend any diagnostics. Underlying illness can worsen quietly during brumation.
Preparing Safely
Before brumation, reptiles need time to empty their digestive tract, so feeding is gradually reduced while they stay warm and hydrated. Temperatures must then be lowered gradually and kept within a safe, stable range, never near freezing.
Monitoring During Brumation
Weigh your reptile regularly and check on them. Significant weight loss, discharge from the eyes or nose, or waking repeatedly are signs to call us.
