When Bronx Zoo-keeper Fred brought home a lion cub, Helen Martini instantly embraced it. The cub's mother lost the instinct to care for him. "Just do for him what you would do with a human baby," Fred suggested...and she did. Helen named him MacArthur, and fed him milk from a bottle and cooed him to sleep in a crib. Soon enough, MacArthur was not the only cub bathed in the tub! The couple continues to raise lion and tiger cubs as their own, until they are old enough to return them to zoos. Helen becomes the first female zookeeper at the Bronx zoo, the keeper of the nursery. This is a terrific non-fiction book to read aloud while snuggling up with your cubs! Filled with adorable baby cats, this is a story about love, dedication, and a new kind of family.
