The Perlipopette cat is an inventor, keen on science and experiments. But his inventions often trigger disasters in shambles. His heating blanket burned his mustaches, his cloud machine created storms and storms... But, persevering, he set about one day creating a lotion of invisibility. Of course, the effect will not be as expected, but it will prove that he was right to try, invent and create! The mad scientist, the wacky inventor, appears here in the Little Cats series with the cat Perlipopette (who we had already met in the Straw Skin cat with another disaster invention). But this story also shows that hard work and perseverance are always rewarded, and that you should always try to make your dreams come true. Text: Stéphanie Dunand-Pallaz.
