I did have a kitty once that was cool with being on a harness. When I took him to the vet he was like a little doggie. I even took him in the car with me. At the time I had stuffed animals on the back dash of my car, and he would hang out back there while i was in the store (don't freak, it'd be like a min or two). Once a lady walked by just as I was getting back in my car and she saw him move, and she was like "OMG I thought that was a stuffed cat!"
Another time, when I took him to the vet, he was cool, hanging out with the other medium sized dogs, then an Akita walked by (who btw didn't even see him) and he FREAKED OUT! That was funny and scary. I got the scars to prove that one.
