Guinea Pigs Cannot Live Alone
Switzerland’s Animal Protection Ordinance, in effect since 2008, mandates that guinea pigs must be kept in pairs or groups. The law applies to other social animals as well, including mice, gerbils, rats, degus, chinchillas, and several bird species like parrots and finches. If a guinea pig’s companion dies, owners must either adopt another or find a new home for the surviving pet.
Hamsters Are the Exception
While many rodents must have company, golden hamsters must be housed alone since they are naturally solitary. Other hamster species, such as Russian dwarf and Chinese hamsters, can be kept in groups, but only under specific conditions.
Rabbits Must Stay Connected
they should be kept in groups whenever possible. If a rabbit must live alone, it must at least be able to hear and smell other rabbits to prevent isolation distress.
No Glasses for Chickens
Swiss law also prohibits forcing domestic poultry to wear glasses or contact lenses. This rule prevents interference with the natural behavior and well-being of chickens and other birds.
Switzerland has some of the most unusual animal protection laws. Guinea pigs can't live alone, rabbits must sense another of their kind, and chickens can't wear glasses. These rules aim to protect animals' well-being, making pet ownership in Switzerland unlike anywhere else.🧵👇 pic.twitter.com/5zzgLPGpSz
