One day, zoo workers found a cardboard box. When they opened it they were shocked, there were 3 little kittens sitting inside. They were small and urgently needed a mother. Zoo staff decided without hesitation that this would be lynx Lena. The little kittens were given into the care of the predator, who happily agreed to become their mother. At first, the lynx treated the babies with some mistrust, but after mutual sniffing and careful study, she began to fulfill the duties of a foster mother. She began to lick the kittens as if they were her own, and did not leave them for a step.
