Commander was my parents` cat but I knew him first. In fact, Commander was my college roommate`s cat. My roommate wanted to sell Commander, but no one would buy him. I called my parents to see if they would like to adopt him. My mom had always loved cats but my dad disliked cats very much. As predicted my dad said, "No way. No cats" Fortunately for me, my dad was out of town at a math conference. So I brought Commander home. By the time he returned, both my mom and Commander had decided that Commander was going to stay. My mom said that Commander was going to live at our house for a "trial period" while we looked for a buyer. As the months went by there was absolutely no effort to sell Commander and it became clear to my dad that Commander was there to stay. Commander started sitting by my dad as he read the newspaper and slowly my dad began to like Commander---just a little bit. By the time I came home that summer, I was surprised to see my dad carrying Commander around the house. Over the years, my parents` love for Commander grew to the point where they could not imagine life without him. Once I finished college, my parents built their dream house and they named the floor plan  The Commander! They worked with the architect to design the house so that it was perfectly suited both for them and for Commander. Commander died at the age of eighteen. My mom still talks about him often and misses him, and so does my dad, which proves that not even the most determined cat-hating human being in the world can resist the charms of a cat once the cat decides he is moving in to your heart.

They designed a room for Commander. They named the floor plan the Commander. They opened a door in the wall for Commander. They worked with the architect to build a cathouse
