I fucked up and let my cat free-roam outside and he was injured by another animal and lost for a week. I will never make that mistake again. It was one of the worst weeks of my life. I’ve learned my lesson.

Now I want to harness train and I was wondering if anyone had tips. He is wearing it at home to cover the wound sites and handling it beautifully. He is 5 years old and healthy/athletic and used to free-roaming so I am worried about taking it outside and having him slip out. Has anyone used a second harness at the same time as a failsafe?
