Grady, my road trip buddy, learning to go for walks with a harness and lead. I’m training him so he can join me in my, soon to be converted, VW Transporter LWB van.
Puppia is the brand of harness I use for Grady. This is the stockist: https://www.puppiaus.com/
And this is where I’ve done most of my adventure cat research: http://www.adventurecats.org/
