It's different all over the world: American child protection social workers responding to a report of seven neglected children found a large alligator in the room with them. I've had dangerous dogs and multiple cats, but in England we don't usually get alligators. Apparently both the children and the alligator were taken into custody (but the alligator separately - its aquarium was filthy, who knows about the children - the newspaper doesn't say).
