Cheetahs who mauled British tourist Violet D'Mello had already attacked an American holidaymaker three years before, according to reports.
Officials at the Kragga Kamma game park in South Africa had said nothing similar to the attack on Mrs D'Mello, in which she suffered wounds to her head, stomach and legs, had ever happened before.
But Michelle Bodenheimer, from Portland Oregon, told the Daily Mail she had been attacked three years ago by the same animals, saying: "I am heartbroken to see that Kragga Kamma did not learn from my unfortunate experience.
"The attacks are not the fault of the cats. They could have been prevented. They are wild animals, which we tend to forget.
"People simply should not be allowed in with these beautiful, wild creatures."
Kragga Kamma manager Mike Cantor admitted he remembered the incident, telling the paper: "We are aware of what Mrs Bodenheimer has said, and I do remember the incident when she was scratched by the cheetahs. They were really young animals then and were particularly playful."
Staff reassured her that two cheetah brothers, Mark and Monty, were hand-reared from birth and completely tame.
Mrs D'Mello, who was taken to hospital immediately after the incident, told the Port Elizabeth Herald newspaper: "It really came from nowhere and I was totally helpless. The doctor at the hospital said cheetahs usually aim for the stomach area and disembowel their victims, so I was lucky to be alive," she said.
"Both cheetahs were on me and there was nothing I could do.They have sharp claws that stick out of their paws and were really strong."
Something inside me just said: "Don't move. Don't move at all. Don't react, just play dead."
"I have had umpteen stitches in my head, my leg and along the side of my stomach."
She added: "This was meant to be a holiday, but it's really turned into a nightmare."
