1. **Behavioral Changes**: If your hedgehog is unusually lethargic, refuses to eat, or is less active than normal, it may be feeling cold. Hedgehogs often curl up into a ball to conserve heat when they are chilly.
2. **Body Temperature**: A healthy hedgehog's body temperature should be around 95-100°F (35-37.8°C). If you suspect your hedgehog is cold, you can use a digital thermometer to check their temperature. If it falls below this range, they may be too cold.
3. **Hibernation Signs**: Hedgehogs may enter a state of hibernation if they are too cold. Look for signs such as deep sleep, a slowed heart rate, or a decrease in breathing rate. If they are hibernating, they may need to be warmed up gradually.
4. **Cold Extremities**: Touch your hedgehog's feet and ears. If they feel cold to the touch, this is a clear indicator that they may be too cold overall.
5. **Nest Building**: If your hedgehog is trying to burrow or build a nest, it may be seeking warmth. Providing additional bedding can help them feel more secure and warm.
To help a cold hedgehog, make sure their environment is warm enough (ideally around 75-80°F or 24-27°C) using heat lamps or heating pads, and ensure they have plenty of bedding to snuggle into. If you are concerned about their health, consult a veterinarian familiar with hedgehogs for further advice.
