12. Hedgehogs (Certain Species)
Although some hedgehogs, such as the African pygmy hedgehog, are popular pets, they come with unique challenges and risks.
These small mammals can carry salmonella, posing health concerns for humans, especially children and those with weakened immune systems.
They also require specialized diets and environments that many owners are unprepared to provide.
Due to these concerns, ownership of certain hedgehog species is restricted or banned in several U.S. states.
The CDC offers more details on the risks and requirements of hedgehog care.
