An irrepressible third grader’s charity pet-sitting business gets out of hand in this witty chapter book.

Marty McGuire really has her hands full this time—with a lazy boa, a hyper hamster, and a potty-mouthed parrot! Is her pet sitting business about to go OUT of business?

After visiting a sanctuary for retired lab chimpanzees, Marty wants to follow in the footsteps of her idol Jane Goodall and help with their care. But “adopting a chimp” is expensive, so Marty and her third-grade pals hatch a plan to raise money by holding a talent show at school and opening a pet-sitting business in Marty’s basement. It turns out that each pet has a personality of its own, and wrangling them is much harder than Marty expected. How will Marty keep her latest great idea from going to the dogs?

Praise for Marty McGuire Has Too Many Pets!

“Messner makes the most of Marty’s story with a nicely differentiated cast of empathetic characters and plenty of dramatic range. The line-and-gray-wash illustrations by Caldecott Medal–winning artist Floca capture moments of anxiety, despair, and happiness with equal grace.” —Booklist
