To care for a pet hedgehog, you would need to provide a suitable habitat that includes a cage with plenty of space for them to move around, a hiding spot, a wheel for exercise, and bedding material such as paper-based bedding. Hedgehogs also need a proper diet of commercial hedgehog food, supplemented with insects like mealworms or crickets. It's important to handle them gently and regularly to help with socialization. Additionally, make sure to keep their environment clean, provide fresh water daily, and take them to a veterinarian experienced with exotic pets for regular check-ups.
