One stormy night, a little black kitten named Peter appears on the museum steps. Tabby cat Tasha is delighted to show Peter the museum's hallways and secret corners, but her siblings, Bianca and Boris, aren't as happy to welcome the new arrival. Determined to prove that Peter is just as much of a museum kitten as the others, Tasha takes him on a hunt for rats. When there's a mishap in the Dinosaur Gallery, all of the kittens must work together to fix the situation. Can they do it?

In this new series from best-selling author, Holly Webb, the Museum Kittens are brave, clever, and never more than a whisker away from adventure! When the museum's visitors are gone for the day, it's time for the kittens to come out and play!
