Corsacs are monogamous and typically form lifelong pairs. Breeding occurs from January to February, often at night, with males vocalizing and competing for females. Mating takes place in a burrow, with a gestation period of 52 to 60 days, resulting in 2 to 16 pups, usually 3 to 6, born in March or April. Newborns are blind, covered in light brown fur, weigh about 60 grams, and measure 13 to 14 cm. They open their eyes around 14 to 16 days and begin eating meat by one month. Young corsacs reach adult size by 4 to 5 months and gather in one burrow for winter. They mature by 9 to 10 months and can live up to 6 years. Corsacs help control rodent populations and are hunted for their fur.
