Well, they actually skirt the rules to stay out of the record books. They say it's good strategy, but I think they're all cheetahs.

They kill the witnesses as well

Sounds about right. In zoos they sometimes pair cheetah cubs with yellow lab puppies to help them deal with the stress of... existing while being a cheetah, I suppose.

There’s a series of photos from a wildlife photographer that are essentially selfies of him with a litter of cheetah cubs that the mother cheetah literally dropped in his lap while she went to go hunt. It’s been theorized that the only reason cheetahs have never been domesticated is that that they’re very difficult to breed in captivity.
