The new rules
As of today, it is only permitted to keep, sell or breed animals that are on the so-called pet and hobby list for mammals. Anyone who has a mammal that is not on the list may keep it until it dies, but breeding with it is no longer permitted.
The new list replaces the positive list for mammals, which until yesterday allowed keeping almost all mammal species. The old list contained 320 mammals, but the new list contains only 30 of them.
There has been a debate for thirty years about which animals are and are not suitable as pets. Six scientists spent five years compiling the new list. A similar list failed in court in 2017 because it was not sufficiently substantiated.
