When she first showed up, we named our new cat Buttercup. We put her in a harness, with a leash attached. We took her to the local Food Co-Op, sat out front on the bench, and held up a sign: "Free Cat-Buttercup. She's a Real Fine Cat!" No one wanted her. So we took her home, re-named her Stinky the Cat, and the rest is Internet history. I'm glad no one took her that day. I would have missed her a lot. We had a good life together.
Now we don't have any cats on a leash anymore.
