1. **High-Quality Cat Food**: Look for dry cat food that is high in protein (over 30%) and fat. This can provide the necessary nutrients for warmth. Brands like Royal Canin or Hill's Science Diet are good choices.
2. **Insects**: Mealworms, crickets, and waxworms are excellent sources of protein and fat. You can offer these as treats or mix them into their regular food.
3. **Cooked Meat**: Small pieces of cooked chicken, turkey, or lean beef can be a great addition. Ensure that it is unseasoned and free from bones.
4. **Specialized Hedgehog Food**: There are commercial hedgehog diets available that are formulated specifically for their nutritional needs, which can also help keep them warm.
5. **Fruits and Vegetables**: While not high in calories, small amounts of fruits like bananas or vegetables like sweet potatoes can be added for variety and some additional nutrients.
6. **Fatty Treats**: Occasionally, you can offer treats like peanut butter (in moderation) or sunflower seeds, as these are high in fat and can help provide extra energy.
Remember to always provide fresh water and monitor their weight, as hedgehogs can easily become overweight. Keeping their environment warm and cozy is also essential, as food alone won't keep them warm if they are in a cold habitat.
