Fido the dog and Whiskers the cat were the best of friends. They lived in a cozy house with their human family, who loved them very much. One day, Fido and Whiskers noticed that their favorite treats had disappeared from the kitchen counter.

"Who could have taken our treats?" Fido asked, his tail wagging in concern. Whiskers just meowed in confusion, her big eyes scanning the room for any clues.

The two friends decided to investigate the mystery. They sniffed around the kitchen, searching for any signs of the missing treats. Suddenly, Whiskers spotted a small paw print on the floor!

"Aha!" exclaimed Fido. "I bet it was that pesky neighbor's cat, Mittens. She's always trying to steal our food!" The two friends set out to find Mittens and get their treats back.
