Donkey believes he's a cat. He lives in a barn, surrounded by cats, and he does everything they do (though balancing on the fence posts is harder than it looks). They're all one big, happy cat family. Until one day, Farmer says something puzzling: "Donkey, you're acting like a cat." And a seed of doubt is planted. Wait -- is it possible that Donkey is not a cat? And does that mean he doesn't belong? When Donkey goes on a journey of self-discovery, he realizes that he knows exactly who he is -- and that he brings something unique and special to the farm.
