Ten Kids, No Pets — Ann M. Martin

WHAT A ROTTEN RULE!
The Rossos have ten kids in their family! That means there's always someone to play with...but it also means a lot of rules. And the worst Rosso rule of all is NO PETS ALLOWED!

It wasn't so bad when they lived in the city. But now that the Rossos live in the country, everyone wants a pet. Woody tries keeping a secret rabbit, Faustine finds some baby birds, and all the kids save Goliath, their Thanksgiving turkey, from ending up on the dinner table.

But a temporary pet just isn't good enough. The Rossos want a real pet, and they're not giving up until they get one!
