Old man Pettson has ten chickens in his hen shed. Findus the cat often teases them and they play chase around the yard. The chickens are Findus's best friends, second only to Pettson. But one day Pettson brings home a rooster for the females. ` Look, we have a rooster', they squawk.' What a handsome fellow he is!' The rooster makes too much noise, and now Findus has no-one to play with. Findus is not happy, but what can he do?
