Cooler months change feeding schedules for a lot of pets on our feeder guides, but not always for the same reason. True brumation is a specific, deliberate dormancy — and it's easy to confuse with an animal simply eating less because its enclosure got colder.
What Brumation Actually Is
Brumation is the reptile version of hibernation — a period of dramatically reduced activity and metabolism, typically triggered by shorter days and cooler temperatures. It's well documented in bearded dragons, and also occurs in species like blue-tongued skinks, red-eared sliders, and box turtles, which brumate seasonally in the wild as a matter of course.
The Feeding Cutoff
Before brumation, feeding should stop roughly two weeks out to let the gut clear completely — undigested food left in a dormant animal's system can rot and make it seriously ill. No feeding happens during brumation itself, and appetite typically returns gradually afterward, sometimes at a reduced level for a while before ramping back to normal. Skipping the pre-brumation fasting window is a common and avoidable mistake.
Not Every Winter Slowdown Is Brumation
Some seasonal feeding changes aren't brumation at all — they're just temperature doing its normal job on an ectotherm's metabolism. A tiger salamander kept below 60–65°F drops to as little as once-a-week feeding, or even once every one to two weeks, without going through anything like a true dormancy period; it's simply eating less because it's colder, not because its body has switched into a distinct brumation state. The practical feeding change looks similar — less food, less often — but there's no pre-fast cutoff or dormancy period to plan around.
Bottom Line
If your pet is a species that truly brumates, plan the two-week pre-fast and don't feed during dormancy. If it's just slowing down with the temperature, scale feeding back gradually instead — check your species' feeder guide to know which situation you're actually managing.
