I tried walking my cat, it did work but the problem was other people walking their dogs and letting them loose in parks. So I stopped going since it terrified him. I tried keeping him in his carrier backpack like thingy, but he still didn’t enjoy it.
Now I have a tuxedo devil kitten, maybe I’ll try it again. Just have to think hard about how and where he can be safe. Maybe just start with his carrier and then move on to the leash?
