Miaow said the Cow

When the cat decides to cast a spell to shut up noisy Cockerel, it has a few side-effects - mice mooing, hens oinking, even the sheep barking at Sheepdog! Cat finds it all very funny until he realises that he's stuck with Cockerel's crow. Wise old Cow sets everything straight, and the farmyard returns to normal, except for naughty Cat.
