Cats in the navy / Scot Christenson.

"Cats were seen as omens in ancient times but eventually became trusted animal companions to those who sailed the seas. From catching rats at docks and on ships at sea, cats often became mascots to the navies around the globe. Filled with informative text and more than eighty photos, Cats in the Navy provides a fun history of our feline friends who rode the waves with us"--Provided by publisher.
