Some Swiss laws re animals

From an essay, "10 Reasons Switzerland Is a Great Place to Be a Pet" by Laura Burge:

Guinea pigs, parrots, and goldfish must have companions, and matchmaking services for guinea pigs have been formed.

Cats need to be able to interact with other cats or at least see other cats from their homes.

Fish also must experience natural day and night cycles.

Rabbits must be able have privacy in their enclosures. In this sense, privacy is a freedom and many other animals other than rabbits also need "to be able to get away from it all" when they choose to do so.

Before bringing a dog into a new home, a person must provide a certificate of competence demonstrating that they know how to deal with and treat dogs. If they can prove that they’ve already had a dog, though, they’re off the hook.

Dogs also must be exercised regularly and be off leash as much as possible. They also must be able to run freely for at least five hours a day and clipping their ears and tails is forbidden.
