Supertramps (2004)

Welcome to the animal underworld. Flea-ridden black cats pretending to bring bad luck for a profit, senile pigeons who've lost the knack of flying, laboratory rats with after-effects and cockroaches determined to make a name for themselves playing the maracas. And things are even worse when the animals come from other countries. Tano (a stray cat), Chung-I Fly (an oriental pigeon), Paulov (an Eastern European rat) and Ramón (a Caribbean cockroach) are all part of this "dispossessed" fauna, whose most prized possessions are their dreams.
