Switzerland’s pet ownership laws

Three guinea pigs

In Switzerland, it is illegal to own only one guinea pig because they’re social animals prone to loneliness. Pet ownership laws don’t stop there. Dog owners have to take classes before getting a furry friend. A cat owner has to let it outside or give it a window from which it can see another cat. Sick fish cannot be flushed down the toilet; special chemicals must be used for euthanasia.
