The cheetah (Acinonyx jubatus) is the world’s fastest land mammal, but its lightweight build and preference for exposed habitats make it susceptible to larger predators. The species is classified as Vulnerable on the IUCN Red List due to global population decline and fragmented habitats. Understanding the reproductive output of the female cheetah provides insight into the immense struggle required to maintain their numbers in the wild. Their strategy must account for a high-risk environment where successful recruitment of new individuals is exceedingly difficult.
The Typical Litter Size
After a gestation period lasting approximately 90 to 98 days, the female cheetah gives birth to a litter of cubs in a secluded den. While litters can range from a single cub up to eight, the typical size is between three and five young.
Surveys of wild populations commonly report the average litter size at birth to be around 3.1 to 3.5 cubs. The female selects a hidden site, such as a rock outcrop or dense vegetation, providing the newborns with their only initial defense. At birth, the cubs are highly dependent, weighing only 150 to 400 grams, and their eyes remain closed for the first four to eleven days. This large initial output is a survival mechanism, ensuring that even a fraction survives the following months.
High Mortality Rates in Early Life
Mortality rates for young cheetahs are exceptionally high, with less than 10% of cubs surviving to reach independence in heavily studied regions like the Serengeti Plains. This low survival rate is driven by external threats, often leading to a death toll exceeding 70% of a litter within the first few months of life.
The overwhelming cause of death is predation from larger carnivores, which view cheetah cubs as easy targets. Lions and spotted hyenas are the primary culprits, actively seeking out and killing the young. Since the mother must leave the den to hunt, the cubs are frequently left unguarded and vulnerable to detection by predators such as leopards, jackals, and honey badgers.
Survival statistics vary significantly depending on the density of competing large predators. In areas where larger carnivores are less prevalent, such as farmlands in Namibia, cub survival rates can be much higher, sometimes reaching over 50%. Other factors contributing to the high attrition rate include disease, exposure to the elements, and the mother’s inexperience. A female must repeatedly produce litters merely to contribute one or two individuals to the adult population over her reproductive lifespan.
The Mother’s Solo Effort and Path to Independence
The task of raising the cubs falls solely to the mother, as the male cheetah plays no part in the rearing process. To protect her vulnerable young, the female frequently moves the den during the first six to eight weeks, carrying the cubs one by one to a new hiding spot. This constant relocation minimizes the scent accumulation that could attract predators.
Cubs begin to follow their mother out of the den when they are about six weeks old, continuously moving with her. The mother’s primary role shifts from providing milk to teaching the complex skills required for survival. She introduces solid food around four months of age and begins crucial hunting instruction.
This teaching phase involves the mother capturing live prey, such as a gazelle fawn, and releasing it so the cubs can practice the chase, trip, and kill sequence. Although they watch her hunt, cubs are not proficient enough to execute a kill independently until they are closer to 12 months old. The lengthy apprenticeship, lasting between 18 and 24 months, is necessary for the surviving young to acquire the sophisticated techniques needed for their future as solitary hunters.
