Metabolic Bone Disease (MBD) in hedgehogs is primarily caused by a deficiency in calcium, vitamin D3, or an imbalance of phosphorus in their diet. Hedgehogs require a balanced diet that includes appropriate levels of these nutrients to maintain strong bones and overall health.

1. **Calcium Deficiency**: Hedgehogs need calcium for bone health. If they do not receive enough calcium from their food, they may develop MBD. This can happen if they are fed a diet that is too high in protein and low in calcium.

2. **Vitamin D3 Deficiency**: Vitamin D3 is essential for the absorption of calcium. Hedgehogs that are kept indoors may not get enough natural sunlight, which is necessary for their bodies to produce vitamin D3. This can lead to poor calcium absorption and contribute to MBD.

3. **Phosphorus Imbalance**: An excess of phosphorus in the diet can also lead to MBD, as it can interfere with calcium absorption. It is important to ensure that the calcium-to-phosphorus ratio in their diet is appropriate (ideally around 2:1).

To prevent MBD, it is crucial to feed hedgehogs a varied diet that includes high-quality commercial hedgehog food, insects, and some fruits and vegetables. Additionally, consider providing a vitamin D3 supplement if your hedgehog is not exposed to natural sunlight. Regular veterinary check-ups can also help monitor their health and prevent nutritional deficiencies.
