Cheetahs breed throughout the year; they are induced ovulators. Females are polyoestrus – they have an oestrus ("heat") cycle every 12 days (this can vary from 10 to 20 days), each oestrus lasting one to three days.
20-23 months old
20 or 23 month
Cubs are born at any time of the year so I'm pretty sure that cheetahs also mate at any time of the year.
Physically they can mate, but no progeny will result
Very few animals will voluntarily breed outside their own species, cheetahs included.
No. Humans are the only animals that go through the marriage ritual. However, cheetahs do mate.
They mate the same way as any other four-legged mammals do.
21 or 22 months of age.
No they don't. They are loners and only look for another to mate.
let two adult cheetahs mate and produce a litter of cubs. Making cheetahs is something nature does by itself.
The urge to mate and breed is a requirement for the survival of the species. If a specie didn't breed it'd die out after one generation.
Cheetahs normally reach maturity between 20 to 24 months. At this stage they are able to hunt well and mate with others.
Female cheetahs reach sexual maturity at an age of 21 or 22 months. Females are induced to ovulate by the mating itself, and have no set ovulation schedule.
No they don't, they are of different species and it is most likely physically impossible.
They sense each other with their smell (nose) and sight (eyes).
