According to the ladies, the tigers were sleeping in the back of the enclosure. When Natasha later returned to the tiger exhibit to take a selfie, one of the animals awoke and started pawing at the glass. "I do believe the tiger knew I was pregnant just by the way it was acting," she said. "I don't know whether to laugh or be scared," a person can be heard saying in the background of the footage. "That's so crazy."
