One small kitten learns about the great big world as he sets sail with his fellow shipmates, animal and human, in this historical fiction intermediate reader. When Trim trips over a napping dog, little does he know that soon he'll set sail and begin learning how to be a ship's cat. Among his first lessons: the parts of the ship (the front is called the bow, like "bow wow"), the dynamics among his new colleagues (Jack the ship's parrot is not so easy to befriend), and basic skills like climbing (up is easier than down) and swimming. With the assistance of Captain Flinders, Penny the ship's dog, and Will the ship's artist, Trim learns new skills, tests his limits and abilities, and finds a way to contribute to life onboard. This delightful early reader series by acclaimed author Deborah Hopkinson is inspired by the true story of Trim, often called the most famous ship's cat in history. Owned by British explorer Matthew Flinders, Trim traveled on the HMS Investigator on the first expedition to circumnavigate Australia (1801-1803).
