Switzerland has an unusual animal welfare law that protects "social animals."
It forbids people from keeping just one of any pet that belongs to a social species such as Guinea Pigs.
The furry rodents get too lonely without a companion.
So, for example, if a guinea pig dies, its owner would be breaking the law by keeping just one remaining pet.
Priska KÃ¼ng came up with a solution for that scenario by setting up a "rent a guinea pig" service. This allows people with only one guinea pig to rent another to keep the surviving pet company.
Anchor Lisa Mullins talks to KÃ¼ng who runs the service in Hinwil, a village near ZÃ¼rich, Switzerland.
