Catnapped

For a whole week, Toriyasu and his little sister, Meeko, have been missing their pet dog, Papadoll. Toriyasu thinks he ran off, but Meeko claims it was an alien abduction. Though Toriyasu mocks Meeko for her over-imaginative ways, she isn't far off from the truth. On the way to school, Meeko sees what looks like a cat in clothes slipping into the shadows. Later that evening, three anthropomorphic feline scientists, Henoji, Suttoboke and HoiHoi go into Toriyasu and Meeko's room intending to take Toriyasu with them on a trip. Instead they end up waking and taking Meeko as well. She accompanies them in their vehicle (a balloon that resembles a cheshire cat) with a tired Toriyasu.
