Pet hedgehogs have several needs to stay healthy and happy. They require a proper enclosure with enough space to move around, a suitable diet that consists of high-quality cat food, insects, and fruits, fresh water at all times, a wheel for exercise, environmental enrichment such as tunnels and hiding spots, and regular veterinary check-ups to ensure their well-being. It's essential to provide a warm and safe environment for your pet hedgehog to thrive.
