Leo is a domestic cat, nice but vain, who shows off like a lion. Suddenly his comfortable life is threatened by the arrival of a new protagonist, a newborn baby who threatens to take his throne away from him. How dare that noisy little being shadow the king of animals? Illustrated album that masterfully shows the process of decoding the image while presenting the changes that occur in the illustration by following the different narrative sequences. A very short text immerses the reader in the inner world of the cat, the fantasy of believing himself to be a lion by the voice that the documentary broadcasts on television.
