“Cheetahs originating from the Southern Hemisphere are biologically programmed to grow thick winter coats during June and July, corresponding to the austral winter.”

At temperate latitudes, most species rely on photoperiod as a cue to time conception, with other cues like rainfall and food availability modulating the impact of photoperiod. However, in this study, areas with aseasonal rainfall in temperate southern Africa showed similar cheetah conception patterns to areas close to the equator. Thus, varying photo‐responsiveness (modulated by rainfall and food availability) may explain the varying cheetah conception between areas with seasonal and aseasonal rainfall.

Cheetah, Acinonyx jubatus, prefer adult prey in the dry season when younger prey are scarce but switch to neonate and juvenile prey during the wet season, presumably to optimize foraging during gestation and lactation.

Some animals can withstand frigid weather, thanks to the insulating properties of the hollow hairs that make up their coats. Little was known about the hairs, but researchers have now discovered that their inner structure changes with the seasons... To determine whether these findings apply to other animals, including predator species such as bears, mountain lions and bobcats, Millett is contacting zoos around the world for hair samples.

Their findings revealed that in regions with seasonal rainfall, over half (58.5%) of conceptions and gestations occurred during the wet season. This timing coincides with an abundance of juvenile prey, which are easier to catch. Interestingly, in aseasonal environments, where rainfall and prey availability are more consistent throughout the year, no distinct breeding pattern was observed.

Cheetahs rely on prey species that have adapted speed and agility to evade them, such as Thomson's gazelles, impalas, and other small to medium antelopes. Cheetahs primarily hunt during the day, preferring early morning or late afternoon when it is cooler.

Some experts believe that the 'winter coat' grown by Southern African cheetahs in anticipation of the cold season there is causing trouble in the warm and moist Indian monsoon. June to August are the winter months in South Africa... Adrian Tordiffe, a veterinary expert from South Africa, said, 'I think the winter coat, plus the constant wet and humid conditions at the moment, and the high parasite load all play a role.'

Officials said the cheetahs imported from South Africa and Namibia unexpectedly grew winter coats during the Indian summer and monsoon, in anticipation of the African winter (June to September)... The winter coat, combined with high humidity and temperatures, caused itching, leading the animals to scratch their necks... He said that India intends to import cheetahs that do not develop thicker winter coats.

The natural process of cheetahs to develop a thick fur coat in anticipation of African winter is proving to be fatal in India's hot and humid climate, news agency PTI quoted experts as saying. In a report to the government, the experts suggested measures such as shaving off the winter coats to prevent fatal infections leading to more deaths.

The central government's ambitious Project Cheetah is facing a major problem, with the animals translocated from South Africa developing a 'winter cover', a thick coat of fur, in anticipation of African winter, the Supreme Court was told on Monday.

Scientists at the University of Edinburgh have determined how animals prepare for seasonal changes, such as growing a warm winter coat, depending on the length of the day. The researchers discovered a biological switch which initiates changes that are critical for survival.

We report here body temperature and locomotor activity measured with implanted data loggers over 7 months in 5 free-living cheetahs in Namibia. Air temperature ranged from a maximum of 39 °C in summer to −2 °C in winter. Cheetahs had higher (~0.4 °C) maximum 24-h body temperatures, later acrophase (~1 h), with larger fluctuations in the range of the 24-h body temperature rhythm (approximately 0.4 °C) during a hot-dry period than during a cool-dry period, but maintained homeothermy irrespective of the climatic conditions.

The cheetah is synonymous with speed. Nature documentaries showcase their agility, reaching up to 80 mph as they chase gazelle in the Serengeti. Their slender bodies, long legs, and specialized muscles enable this explosive sprint.

Experts believe that cheetahs develop winter coats as they prepare themselves for the African winter which takes place from June to September. India is thinking of importing cheetahs from Northern Africa because of concerns regarding the ability of the big cats from Namibia and South Africa to adapt after they developed a winter coat during the scorching Indian summer.

Changing to a new fur coat is one of various adaptations used by mammals that are active year-round in Illinois to cope with winter. In more northern latitudes, shorter days and falling temperatures leads many weasels to change from their summer brown/tan coat to a white coat for winter.

Due to their colder climate habitat, snow leopards exhibit several adaptations for surviving harsh weather conditions. Their stocky bodies, thick fur, and small, rounded ears are all designed to minimize heat loss. To help deal with the climate change in their environment, these cats will grow a thicker coat for the winter months.

Many mammal species living in temperate or polar regions exhibit seasonal changes in their fur density and color, a process often triggered by photoperiod (day length) and temperature. This adaptation, controlled by hormonal responses, allows them to optimize insulation for winter and camouflage for different seasons. The austral winter in the Southern Hemisphere occurs during June, July, and August, characterized by shorter days and colder temperatures.
