The little girl has never seen a barn owl, but one day her grandpa puts a nest-box high in the old oak tree. They wait and they wait until one spring night, just as the sky goes pink, a pale face looks out of it, then takes off towards them.
Cat wishes he could fly just like his best friend, Canary. Then one day he gets tangled up in a kite, and soon he is flying high in the sky! He sees many wonderful things, but then the wind blows stronger and a storm appears. Cat is unable to control the kite and he is carried far from home. Can anyone save him?
