The Minaduki family attempts to resume life as usual with the new kitten as a new member, but the elusive and fickle kitten causes everyone to worry. Chocola, especially, can't seem to concentrate on anything.

Kashou is worried about something, which worries the cats. Chocola and Vanilla decide to take matters into their own hands and help. Cacao sees the elder cats spring into action, and decides to help in her own way, too.

A storm arrives, and the cats prepare the house in case things get very rough. Both of the humans in the Minaduki household are away, so the cats must stay at home by themselves.
