In a zoo in
The mother tiger after recovering from the delivery, suddenly started to decline in health, although physically fine. 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. The veterinarians decided to try something that had never been tried in a zoo environment.Sometimes a mother of one species will take on the care of a different species. The only "orphans" that could be found quickly, were a litter of wiener pigs. The zoo keepers and vets wrapped the piglets in tiger skin and placed the babies around the mother tiger.
