Thread: Car Training and Leash Training

I don't know your location but in the UK it is illegal to have unrestrained pets in a car. I'd stick with getting him used to travelling in his carrier, door closed. The carrier also has to be secured with the seatbelt.

If he is comfortable in the harness just persevere with that for a while and then after some time, attach the leash and carry him outdoors without walking him on the leash. Eventually he'll get the association of leash and outdoors but I don't think cats ever take to it quite as naturally as dogs.
