Domesticated hedgehog

life science Maturity 5-7 Next article →

Domesticated hedgehogs are small animals kept in homes as pets. Most people who own them keep the African pygmy hedgehog, known scientifically as *Atelerix albiventris*. This species comes from warm climates where temperatures stay high. Other species sometimes kept as pets include the long-eared hedgehog and the Indian long-eared hedgehog.

Because African pygmy hedgehogs are from warm areas, they do not hibernate in the wild. If their body temperature drops too low, they may begin a hibernation process. This can lead to death unless the animal is warmed up within a few days. Modern breeding has also created new color patterns. Some hedgehogs are albino, meaning they lack color. Others are pinto, which is a pattern of distinct patches with no color on the quills or skin.

Taking care of a hedgehog requires specific dietary and physical needs. Hedgehogs are insectivores, meaning their diet consists mostly of insects. They require food that is high in protein but low in fat. They also need chitin, which is a substance found in the exoskeleton of insects. Owners can provide chitin through special prepared foods or alimentary powders.

While they can eat small amounts of vegetables, fruit, or lean meats like chicken, they are lactose-intolerant. Consuming most dairy products will cause stomach problems. Physical activity is also vital for their health. In the wild, hedgehogs cover many miles each night. In a cage, they need a solid running wheel, ideally about 12 inches in diameter, to prevent obesity and liver problems. If a hedgehog becomes too obese, it may lose the ability to roll into a complete ball.

Humans have interacted with hedgehogs for thousands of years. Ancient Greeks may have kept them to control pests like beetles. Aristotle and Plutarch recorded accounts of hedgehogs being kept in homes, sometimes even used to predict the weather. In the 4th century BCE, the Romans domesticated a relative of the Algerian hedgehog. They used these animals for meat and for their quills. Hedgehog skins were even used to clean shawls, making them important for commerce. The Roman Senate even created regulations to manage the trade of these skins. Quills were also used as tools in training other animals, such as preventing a calf from suckling after weaning.

Legal rules for owning hedgehogs vary significantly around the world. In the United States, popularity for these pets grew in the early 1980s. However, some states ban them or require licenses. Some restrictions exist because certain species can carry foot and mouth disease. This is a highly contagious disease that affects cloven-hooved animals. In Australia, all hedgehogs are classified as exotic pets and are illegal to import. In New Zealand, they are listed as a destructive pest. Some jurisdictions in North America require specific licenses to legally breed them.

Many countries in Europe have strict protections for the European hedgehog. This species is protected by the Berne Convention, which includes many member states of the Council of Europe and the European Union. In most of these countries, it is illegal to capture or keep a European hedgehog as a pet. For example, in Austria, Denmark, Finland, Italy, Latvia, Poland, and the United Kingdom, the European hedgehog is protected. In these locations, the four-toed hedgehog is often the species that is legally allowed as a pet. However, rules change by specific location. In France, no hedgehog species may be kept as a pet. In Spain, the four-toed hedgehog is considered an illegal exotic invasive species. In the Netherlands, the sale and breeding of four-toed hedgehogs became illegal on January 1, 2024.

Health and safety are important considerations for owners. It is rare for a person to be allergic to the hedgehog itself. Some people report pink dots on their hands, but this is usually caused by small pricks from the spines rather than an allergy.

Owners should wash their hands after handling them to avoid infections from contaminants. Bedding choice is also critical for respiratory health. Wood oils from cedar can cause severe breathing problems, so owners should use aspen instead. Hedgehogs can also suffer from Wobbly Hedgehog Syndrome, or WHS. This is a neurological problem that may be caused by a genetic flaw allowing a virus to attack the nervous system. Other health issues include cancer, obesity, and bacterial pneumonia, which causes sneezing or bubbles around the nose.

Understanding hedgehogs requires looking at how they interact with their environment and human systems. Their need for specific habitats relates to the biological concept of climate adaptation. The legal status of hedgehogs connects to ecology and the management of invasive species. When an animal is moved to a new area, it can affect the local ecosystem, which is why some countries classify them as pests. By studying these animals, we learn more about how biology, law, and human history all overlap in the lives of small creatures.
