Moxie is Will's cat. Her favorite spot is under the Hydrangea bush in the front yeard of his house. She is a tabby like the cat that leads Will into Cittàgazze. Despite the alethiometer's identification of Will Parry as a murderer, it was actually an accident. Will had jumped into the man and Moxie was standing behind the man's legs, waiting to be petted, and the man tripped over her and fell down the stairs.
