I take a soft-sided wheeled carrier with me when I walk Atticus. He's still getting used to the leash, doesn't like traffic, and is uncomfortable meeting strangers unless he is within 3 ft. of our driveway. If he gets too scared or too interested in something, I put the carrier down and he'll get in. Then I can wheel him home. He weighs nearly 23 pounds so I don't want to be carrying him over any distance. With a lighter cat, a regular soft carrier will do nicely. You can also buy a pet stroller and walk her along with it and put her in it when need be.
