"My friend bought one of these for her new kitty, and she walks her with my Dog and we get so many comments on the crazy pair!
I saw how well it worked and bought one for my rabbit. (A medium size works well for a mini-lop.) It works so well! It doesn't put any pressure on the throat like those simple slip rope harness for small animals. (My bunny managed to get one of those to pull too hard on his neck in the past, so I was on the hunt for a new harness anyways.)
A useful tip though, is to put this with a flexi-lead, because the bungee leash isn't long enough for a kitty or a bunny the way they like to bound ahead and then stop to wait for you to catch up.
Still it's the best harness I've ever used, I would definately recommend it to anyone with a small animal!"
