Do you know the best kind of harness to buy? I bought one that was recommended at a pet shop and is adjustable, but once while I was getting my cats used to it indoors, one of them managed to squirm out of it. It was the first time I put it on, so it could be that it wasn't adjusted close enough around the neck (plastic piece that holds nylon bands goes on back of neck area). But I got worried. I live in a city and near traffic areas, and if they got away it could be really awful. And how wide do you think the nylon leash should be? I got a fairly narrow one and hope it is OK. What do you think are the best harnesses and leashes??? I also have no idea what my cats would do if they ever got away... Do they usually just run, or do they sometimes stick closer to home? I have been really afraid to take them outside, but with the weather so nice now, I would like them to be able to enjoy it some. Thanks for your help.
