A British study found that female cheetahs in Tanzania are prone to infidelity -- having cubs with several different fathers.
Although the practice is rare among other big cats, the researchers said DNA analysis of the speedy cats found that nearly half of the litters analyzed contained cubs from multiple different fathers, the BBC reported Wednesday.
The researchers said the infidelity could expose the animals to disease but it could also help the endangered species ensure genetic diversity.
"If the cubs are genetically more variable it may allow them to adapt and evolve to different circumstances," said one of the scientists involved in the study, Dada Gottelli of the Zoological Society of London.
"If there is a big change in the environment some may be able to cope better."
The scientists studied 176 cheetahs for about nine years and found that of the 47 litters of cubs born in that time, 43 percent contained cubs from different fathers.
"If anything, this is an underestimate," Gotelli said. "Cheetah cubs suffer high mortality in the first few weeks so it was difficult to get samples from all of them."
