The Fox and the Hare (1973)

Original title: Лиса и заяц

As winter gives way to spring in the Russian wilderness, a crafty fox promptly expels a defenceless hare from his warm, comfortable residence, claiming the house for himself and leaving the poor owner to sleep outside under the stars. An assortment of compassionate animals – a wolf, a bear, a bull – take pity on the disheartened hare, and attempt to evict the cunning fox, but to no avail. Along comes a hilariously militant rooster, proud and tenacious, who marches into the hare's house and doesn't give up until the fox has been hounded back into the wilderness.
