1. **Quilling**: While quilling is a natural process for young hedgehogs, excessive quilling in adults can indicate stress.
2. **Hissing or Puffing Up**: When a hedgehog feels threatened or stressed, it may hiss or puff up its quills as a defensive mechanism.
3. **Increased Hiding**: If your hedgehog is spending more time hiding than usual, it may be feeling stressed or insecure in its environment.
4. **Aggressive Behavior**: A normally docile hedgehog may become aggressive, biting or scratching when stressed.
5. **Loss of Appetite**: A stressed hedgehog may refuse to eat or drink, which can lead to health issues if not addressed.
6. **Excessive Grooming**: Over-grooming can be a sign of stress, leading to bald patches or skin irritation.
7. **Vocalizations**: Unusual vocalizations, such as whining or squeaking, can indicate discomfort or stress.
8. **Changes in Litter Box Habits**: If your hedgehog is suddenly not using its litter box, it might be a sign of stress or health issues.
To help alleviate stress, ensure your hedgehog has a comfortable environment, a proper diet, and regular interaction. Reducing loud noises and sudden movements around their habitat can also help create a more calming atmosphere. If stress persists, consider consulting a veterinarian specialized in exotic pets for further advice.
