Oestrus in female sand cats lasts from five to six days, during which they frequently call and scent mark. After a gestation of 59 to 66 days, they give birth to a litter of two to three kittens. The kittens weigh at birth, and have spotted pale yellow or reddish fur. They grow relatively rapidly, reaching three quarters of the adult size within five months, are fully independent by the end of their first year and reach sexual maturity soon after the first year.
