A pet hedgehog is a small, nocturnal mammal that has become popular as a household pet. They are known for their spiky quills, which serve as a defense mechanism against predators. Hedgehogs are generally solitary animals and require a suitable habitat that includes a spacious cage, bedding, and hiding spots. These animals are insectivores, primarily feeding on insects, but they can also enjoy a diet of specially formulated hedgehog food, fruits, and vegetables. It's important for owners to provide proper care, including regular veterinary check-ups, to ensure the health and well-being of their hedgehog.
