Ali sat on her bed. She picked up Tedward Bear. "I wish I had a big brother who wasn't allergic to cats," she whispered in his ear. "I wish I had a baby brother who didn't take my things." She hugged Tedward Bear. "But most of all, I wish I could have a real cat of my very own." Ali wants a pet cat for her birthday, but her brother Jay is allergic to cats. Ali's clubhouse, hidden among the trees in her backyard, is her favorite place to play. The only other person she shares it with is her best friend Sam. One day, Ali discovers that something else is sharing the clubhouse too-a beautiful white cat she names Snowy. But is Snowy really Ali's cat to keep?
