When Suzannah arrives to volunteer at the shelter, one of the animals is missing! It's Merlin, a mischievous ferret who gets into everything, and loves to play hide and seek.

Owning a ferret can be really hard work, the Shelter Pet Squad discovers. Whoever takes Merlin home will need to be prepared. That's why Suzannah and the other kids make up a test to give to anyone who wants to adopt him. But the ferret is full of surprises . . . and even the Shelter Pet Squad has a lot to learn.
