1. **Hissing or Quilling**: If your hedgehog hisses or makes other vocalizations, it might be feeling threatened or uncomfortable. Quilling, which is the process of losing baby spines and growing new ones, can also cause discomfort, leading to irritability.
2. **Curling Up**: When hedgehogs feel scared or in pain, they often curl into a tight ball. This behavior is a natural defense mechanism, and it can indicate that they are feeling stressed or threatened.
3. **Aggressive Behavior**: If your hedgehog suddenly becomes aggressive, such as biting or scratching, it may be a sign of discomfort. This could be due to pain, illness, or feeling cornered.
4. **Change in Appetite**: A sudden decrease in appetite or refusal to eat can indicate discomfort or health issues. If your hedgehog is not eating, it’s important to investigate further.
5. **Lethargy**: If your hedgehog is unusually inactive or lethargic, it could be a sign of illness or discomfort. Healthy hedgehogs are typically curious and active, so a noticeable change in behavior can be concerning.
6. **Excessive Grooming**: If you notice your hedgehog grooming itself excessively, it may be trying to soothe an irritation or discomfort caused by skin issues or parasites.
7. **Abnormal Posture**: If your hedgehog is hunched over or has a stiff posture, it may be experiencing pain or discomfort.
If you observe any of these signs, it’s important to consult a veterinarian who specializes in exotic pets to ensure your hedgehog receives the appropriate care and treatment.
