Yes, there are several foods that are toxic to hedgehogs and should be avoided to keep them healthy. Here are some of the most common toxic foods:

1. **Chocolate**: Like many pets, hedgehogs should never be given chocolate as it contains theobromine, which is toxic to them.

2. **Onions and Garlic**: These can cause gastrointestinal upset and damage to red blood cells, leading to anemia.

3. **Citrus Fruits**: While some fruits are safe, citrus fruits like oranges, lemons, and limes can cause digestive issues.

4. **Avocado**: The pit and skin contain persin, which is toxic to many animals, including hedgehogs.

5. **Raw Meat and Fish**: These can carry harmful bacteria and parasites, so it's best to avoid feeding them raw.

6. **Dairy Products**: Hedgehogs are lactose intolerant, and feeding them dairy can lead to digestive problems.

7. **Nuts and Seeds**: These can be choking hazards and may not be digestible for hedgehogs.

Always stick to a balanced diet of high-quality hedgehog food, insects, and safe fruits and vegetables. When in doubt, consult with a veterinarian who specializes in exotic pets for guidance on proper nutrition.
