Once upon a time, there was a thin cat named Tim. Tim liked to watch the birds outside his window. One day, Tim saw a big dog named Max doing exercise in the yard.
Tim wanted to play with Max, so he opened the door and went outside. Max saw Tim and said, "Hi, Tim! Want to do exercise with me?" Tim said, "Yes, let's play!" They started to run and jump together.
But then, a big bird saw Tim and Max playing. The bird was angry because it thought they were too loud. The bird flew down and took Tim away. Max tried to save Tim, but he was too slow. Tim was never seen again, and Max was very sad.
