I had posted awhile back that I was intending to try to leash-train my cat, Murray. So far we are making some progress. I had ordered a walking jacket, and the first one I ordered was too small, but I returned it and got the extra-large size, and that one fits Murray great. I've tried the jacket on Murray for the past several days, for just a few minutes at a time, and he seems to be getting a little more comfortable with it, though it still feels a little strange (instead of walking normally with it on, he sort of "slinks" around). If he doesn't seem completely comfortable with it several weeks from now, I will return it. But hopefully his comfort level will continue to grow, and once he is used to the jacket I will try it with the leash, and once he is used to the leash I will try holding the leash and see what happens. Slowly but surely...
