'Felix might be a big fat cat, but he is not the one who ate the last of the strawberry jam and made Grandma cross! So when everyone's asleep, Felix goes out hunting for the thief - and finds him at the bottom of the strawberry jam jar. He pounces but his head is too big - and gets stuck! Poor Felix - and poor little mouse, who is trapped in the jar. What are they going to do? Grandma and Grandpa and Molly can't get the jar off, no matter how hard they try, but clever Felix finds a way - he hits the jar against the ground and it breaks, freeing the mouse and Felix. Now everyone can go back to bed'--Provided by publisher.
