If a hedgehog is underweight before hibernation, it can face several serious health risks. Hedgehogs typically need to accumulate enough fat reserves to sustain them through the hibernation period, which can last several months. If they enter hibernation without sufficient weight, they may not have enough energy to survive, leading to potential starvation, dehydration, or even death.

To prevent this, it’s crucial to monitor your hedgehog's weight leading up to hibernation. A healthy adult hedgehog should weigh at least 600 grams before hibernation. If your hedgehog is underweight, consider the following tips to help them gain weight:

1. **Diet Adjustment**: Offer a high-quality, protein-rich diet. Foods like high-quality cat food, insects (like mealworms), and even cooked meats can help. You can also provide specialized hedgehog food that is designed to meet their nutritional needs.

2. **Frequent Feeding**: Increase the frequency of feedings. Instead of one or two meals a day, try offering smaller portions multiple times a day to encourage eating.

3. **Supplementation**: Consider using dietary supplements or high-calorie treats to boost their caloric intake. Products specifically made for hedgehogs can be beneficial.

4. **Warm Environment**: Ensure that your hedgehog is kept in a warm environment to encourage eating and activity, as cold temperatures can make them lethargic.

5. **Veterinary Consultation**: If your hedgehog is significantly underweight or not gaining weight despite dietary changes, consult with a veterinarian who specializes in exotic pets. They can rule out any underlying health issues and provide tailored advice.

By ensuring your hedgehog reaches a healthy weight before hibernation, you can help them have a safe and successful hibernation period.
