My story

 MiMi was the only yellow in the litter and she was the first born. Even before her eyes opened, she seemed to know she was different, and tended not to pile in with her black littermates. I know this happens, one color segregating itself from another within a litter, but how does it happen when they can even see each other yet? I don't know if it was her innate charm, because she's the pick girl, or simply because she was the only yellow in a field of blacks, but everyone was immediately drawn to her. An eye catcher and she seemed to know it. Her attitude has always been that of knowing somehow she was special. I think the name suits her.
