As days shorten and temperatures drop, many pet reptiles enter a period of reduced activity, decreased appetite, and prolonged sleep called brumation. Understanding this natural process prevents unnecessary worry and helps you support your reptile through this dormant period.

What Is Brumation

Brumation is the reptile equivalent of mammalian hibernation, though there are important differences. Unlike true hibernation, brumating reptiles may periodically wake to drink water and may shift positions within their enclosure. Body functions slow dramatically but do not cease entirely.

Species That Brumate

Bearded dragons, blue-tongued skinks, many tortoise species, box turtles, and temperate-zone snakes commonly brumate. Tropical species like crested geckos and ball pythons do not typically brumate, though they may show seasonal appetite reduction. The tendency varies by species origin and individual.

Signs of Brumation

Gradual decrease in appetite over days to weeks, increased sleeping or hiding, reduced activity levels, preference for cooler areas of the enclosure, and reduced responsiveness are all normal brumation indicators. These changes are gradual, not sudden. Sudden lethargy could indicate illness rather than brumation.

Brumation vs. Illness

The key distinction is gradual onset versus sudden change. A healthy reptile entering brumation slowly reduces activity and appetite over one to two weeks while maintaining normal body weight and condition. Illness typically involves more rapid changes accompanied by weight loss, abnormal posture, discharge, or other symptoms.

Husbandry During Brumation

Continue providing fresh water at all times. Reduce lighting to match natural shorter day lengths. Allow the cool side temperature to drop slightly while maintaining a minimum safe temperature for your species. Do not force-feed a brumating reptile, but continue offering food weekly in case they want it.

Duration and Recovery

Brumation typically lasts four to twelve weeks depending on species and individual variation. As day length increases in spring, reptiles gradually resume normal activity and appetite. Allow natural emergence rather than forcing your reptile out of brumation with dramatic temperature or lighting changes.
