Hibernation and torpor are both natural physiological responses in hedgehogs to conserve energy during periods of cold or food scarcity, but there are key differences between the two. Hibernation is a long-term state of reduced metabolic activity that can last for weeks to months. During hibernation, hedgehogs enter a deep sleep-like state where their body temperature drops significantly, their heart rate slows down, and they rarely wake up to eat or drink. On the other hand, torpor is a short-term state of decreased activity and metabolism that can last for a few hours to a few days. Hedgehogs in torpor can still wake up to eat, drink, or move around, unlike in hibernation where they remain in a prolonged state of dormancy. Torpor is more of a daily or periodic cycle that hedgehogs enter to conserve energy without completely shutting down their bodily functions like in hibernation.
