Tom Brand (Kevin Spacey) is undeniably successful, impossibly wealthy, and an unapologetic jerk. Striving to build the tallest skyscraper in the Northern Hemisphere, the daredevil billionaire will sacrifice anything even the love of his family to complete an architectural marvel nearly as gargantuan as his ego. Toms workaholic lifestyle has alienated his long-suffering family, including his devoted wife Lara (Jennifer Garner), neglected adult son David (Robbie Amell) and starved-for-attention young daughter Rebecca (Malina Weissman). When Rebeccas 11th birthday arrives, the girl begs her father for the same present she asks for every year: a cat. Tom hates cats, but reluctantly finds himself in a magical pet shop owned by the quirky Felix Perkins (Christopher Walken). The peculiar proprietor knows exactly what Brand needs and its name is Mr. Fuzzypants. After suffering a fateful accident on the way to Rebeccas birthday party, a horrified Tom discovers that while his human form is lying comatose in a hospital bed, he is watching events unfold from inside the body of the cat. Trapped inside Mr. Fuzzypants and trying desperately to make his loved ones aware of his situation, he soon realizes that if he is ever to earn back his human existence, he must reconnect with his family and become the husband and father they deserve.
