One day, a lovely cat named Kitty was walking down the street. She saw a police car with its lights on. Kitty was very curious and wanted to see what was happening. She walked up to the police car and saw a big dog inside. The dog was wearing a police hat and looked very important.
Kitty thought the dog was in trouble, but then the dog started to laugh. He said, "I'm not in trouble, I am a police dog! My job is to help the police." Kitty was surprised and didn't know that dogs could be police too. She thought it was funny and started to laugh with the police dog.
From that day on, Kitty and the police dog became good friends. They would play and laugh together every day. Kitty learned that not everything is what it seems at first, and that even dogs can have important jobs. And the police dog learned that cats can be lovely friends too.
