Animals.

A rat gets mating tips from his friend at a subterranean party; a pair of police horses complains about an old acquaintance; a bedbug has a midlife crisis.

A naive male pigeon prepares himself for motherhood; a pigeon is challenged by a New Jersey rival; one caterpillar's metamorphosis is another's lament.

Two privileged feline siblings find their perfect day interrupted by an alley cat; a goose grows bored with the monotony of his life and attempts to bond with a flock of Central Park swans.

A papillon is thrust into an unwelcoming dog park; a dog-walking group deals with an unexpected secret; two dogs dissect their owners' first date.

A rat invents pants; a moth tries neon light for the first time; two fish couples endure a tense dinner.
