Waiting on customers

I have a cat. Her name is Mimi. Her eyes are very beautiful because they are two different colo(u)rsーblue and green.
Ten years ago, I found her by the side of a river/beside a river. She was abandoned and alone. I thought I had to help her. Now, she lives without being alone. She is a member of my family.
