Yes, hedgehogs can get injured on wheels, particularly if the wheel isn't designed specifically for them. Traditional hamster wheels can pose risks such as:

1. **Size**: If the wheel is too small, the hedgehog may struggle to run comfortably, leading to potential injuries.

2. **Material**: Wheels made of wire can cause injuries to their feet or legs. It's best to use solid, flat surfaces that provide good traction.

3. **Safety Features**: Look for wheels that have safety features, such as a closed design that prevents their limbs from getting caught.

4. **Supervision**: Always supervise your hedgehog when they are using a wheel to ensure they are safe and not getting into any trouble.

5. **Alternatives**: If you're concerned about injuries, consider providing other forms of exercise, like a safe play area or tunnels for exploration.

By ensuring that the wheel is appropriate for their size and safe in design, you can help prevent injuries and promote a fun exercise routine for your hedgehog!
