A lively tale about a fun-loving cat learning to accept change, imaginatively illustrated by the award-winning Petr Horacek.

Mischievous Mister Boo loves to give everyone he meets a surprise. He shocks the baby birds, the baby rabbits and the baby owls. BOO! But one day he wakes up without his usual energy and no one seems to take any notice of him. Will Mister Boo learn to accept change and find joy again? A buoyant second collaboration between the acclaimed writer Joyce Dunbar and world-renowned illustrator Petr Horacek.
