Hedgehogs are sensitive to temperature changes, and it's important to ensure they are kept in a warm environment to prevent cold stress. Here are some signs that your hedgehog may be feeling cold:

1. **Huddling or Curling Up**: If your hedgehog is constantly curled up in a tight ball or huddling in a corner of their habitat, it may be trying to conserve heat.

2. **Reduced Activity**: Cold hedgehogs tend to be less active. If you notice your hedgehog is lethargic or not exploring as usual, it might be feeling chilly.

3. **Cold Skin**: You can gently touch your hedgehog's skin to check for temperature. If it feels noticeably cooler than normal, this is a sign that it may be too cold.

4. **Shivering**: Just like humans, hedgehogs may shiver when they are cold. If you observe this behavior, it’s a clear indication that your hedgehog is uncomfortable due to low temperatures.

5. **Nasal Discharge**: Cold stress can sometimes lead to respiratory issues. If you notice your hedgehog has a runny nose or any unusual discharge, it could be a sign of stress from the cold.

To ensure your hedgehog stays warm, maintain a temperature range of 72°F to 80°F (22°C to 27°C) in their habitat. You can use heating pads, heat lamps, or ceramic heat emitters to provide additional warmth, but make sure there are no hot spots that could burn your hedgehog. Always monitor the temperature with a reliable thermometer to keep it within the ideal range.

Additionally, providing plenty of bedding material can help your hedgehog burrow and retain heat. This can include fleece blankets or shredded paper, which can also make their environment cozy and comfortable.
