The Secret Life of Pets : The quiet life of a terrier named Max is upended when his owner takes in Duke, a stray whom Max instantly dislikes. They are rescued by a rabbit named Snowball, the leader of “The Flushed Pets” – a gang of sewer-dwelling animals who hate humans because their owners abandoned and mistreated them. After Max and Duke pretend to despise humans as much as they do, the Flushed Pets invite them to join. Before they can prove their loyalty by allowing a one-fanged viper to bite them, Snowball learns from the cats that Max and Duke are domesticated. The two dogs escape the sewers and board a ferry to Brooklyn, inadvertently killing the viper in the process; Snowball vows to kill them and leads the Flushed Pets after them.
