Brumation is a period of winter dormancy in snakes, marked by reduced activity, appetite, and metabolism in response to cooler temperatures and shorter days.
Also known as: Winter dormancy, Reptile hibernation.
Why brumation matters
Brumation is the reptile equivalent of hibernation, but the animal does not truly sleep — it slows down, hides more, and often refuses food for weeks or months. It is a normal seasonal response, not an illness, and for many species it is a prerequisite for successful breeding. The challenge for keepers is telling a healthy brumation apart from a genuine loss of appetite caused by stress, illness, or incorrect temperatures.
Common signs
- Sharply reduced or absent appetite as temperatures drop
- More time spent hidden or burrowed in the substrate
- Lower activity and slower movement when handled
- Maintained body weight despite not eating — a fasting snake should not waste away
What to do
Confirm the snake is at a healthy weight before brumation begins, and never brumate a sick or underweight animal. Continue offering fresh water at all times, since dehydration is the main risk during a long fast. Keep handling to a minimum and let the snake set the pace. If weight drops noticeably or the snake seems unwell rather than simply slow, treat it as a health concern and consult a reptile vet.
How to track brumation in Snakey
Snakey’s feeding and weight logs make brumation easy to monitor: a stretch of declined feedings paired with a stable weight curve is the expected pattern, while declined feedings alongside falling weight is the warning sign to act on. Logging through the season gives you a clear baseline to compare against next year.
