A tiger mother lost her cubs from premature labour. Shortly after she became depressed and her health declined, and she was diagnosed with depression. So they wrapped up piglets in tiger cloth, and gave them to the tiger. The tiger now loves these pigs and treats them like her babies.
The veterinarians felt that the loss of her litter had caused the tigress to fall into a depression. The doctors decided that if the tigress could surrogate another mother's cubs, perhaps she would improve. After checking with many other zoos across the country, the depressing news was that there were no tiger cubs of the right age to introduce to the mourning mother..
