Loki (Our half ferral, Westray, long haired cat) is lead trained.He has been since he arrived at 8 weeks five years ago. He travels with us in the camper or the car. We have long leads in the garden which he is attached to when he goes outside. More often, just open the door and he runs to the camper meowing to be let in !! He will spend all day inside the camper. Water and food and his outside litter tray are always there for him. If he "escapes" out through the door, he runs to the camper. He's travelled thousands of miles and for weeks at a time. He sits by Aragon (The lab) when they are both on the grass. He never attacks birds or anything else either.
