Hedgehogs are typically nocturnal animals, meaning they are active at night and rest during the day. However, if a hedgehog is seen moving around in full daylight—without hiding or showing fear—it can be a sign of physiological distress. This might include conditions such as hunger, injury, or the presence of parasites. Such behavior is particularly concerning in early September, as this is a crucial time for hedgehogs to build up enough fat reserves to survive the winter hibernation period. Hibernation is a survival strategy that allows hedgehogs to endure the cold months without eating or drinking. To do this, they must reach a minimum weight of 600 grams by late September. If a hedgehog weighs less than this, its chances of surviving hibernation are significantly reduced. This weight threshold corresponds to the minimal fat mass needed to sustain the animal through several months of inactivity. Therefore, identifying a thin or weakened hedgehog in late August to late September is critical, as this is the last opportunity for them to catch up on their fat reserves before the cold weather sets in. If you encounter a hedgehog that appears to be in distress, the best course of action is to place it in a quiet cardboard box and contact a wildlife rescue center immediately. These centers are equipped to provide the necessary care and support for injured or underweight animals. In urban and suburban areas, gardens have become vital habitats for hedgehogs. Simple actions, such as leaving a pile of dead leaves or creating a small passage in a fence, can provide essential shelter for these animals during the winter months. As autumn approaches, observing a hedgehog's body condition can help determine if it is in need of assistance. If a hedgehog appears visibly thin, weighing it—when possible without causing it stress—or assessing its overall body condition can offer a quick evaluation of its health. Prompt contact with a wildlife rescue center is the most effective way to ensure the animal receives the care it needs. This is especially important during the critical period of late August to late September, when the survival of a hedgehog can depend on timely intervention.
