1. **Huddling**: If your hedgehog is curling up tightly in a ball or huddling in a corner of their enclosure, it may be trying to conserve body heat.
2. **Reduced Activity**: Cold hedgehogs often become lethargic and may not explore their environment as usual. If your hedgehog is spending excessive time sleeping or hiding, it could be a sign that they are feeling chilly.
3. **Cold Body Temperature**: You can gently feel your hedgehog's body; if it feels cold to the touch compared to normal, it may be too cold. A healthy hedgehog's body temperature should be around 95-100°F (35-37.5°C).
4. **Shivering or Trembling**: Like many animals, hedgehogs may shiver when they are cold. If you notice any trembling, it’s time to warm them up.
5. **Nasal Discharge**: If your hedgehog has a runny nose or seems to be sneezing, it could be a sign of respiratory issues often exacerbated by cold temperatures.
To help keep your hedgehog warm, ensure their habitat is at an appropriate temperature (around 75-80°F or 24-27°C) and consider using a heating pad or a ceramic heat emitter to provide gentle warmth. Always ensure that any heating source is safe and does not cause overheating.
Additionally, providing nesting materials like fleece or shredded paper can help them stay warm and cozy. If you suspect your hedgehog is too cold and doesn’t respond to warming efforts, it’s important to consult a veterinarian for further advice.
