It is said that the previous estimates of the population of cheetahs needed for them to survive a natural disaster were understated and yet on top of that, the current population barely meets those understated numbers. Their numbers are therefore not enough to survive a natural disaster as it is.
To top that all of, the population cannot increase in the short term because African grasslands cannot support a larger population. This means that should a natural disaster strike Cheetahs in the short term, their numbers would be unable to take it and they would not survive.
