During Newsfeed on Net TV it was pointed out that the cubs of tigers born in captivity would not be able to survive if they were left free. This is because they were never taught how to hunt for their food and where to shelter in rough weather.
It is important to understand it is necessary for tigers to be kept in open areas where they can roam about and hunt so that their hunting instinct remains intact.
Tigers in captivity can suffer terribly, especially from stress. Thousands of tigers and other big cats are kept in appalling conditions in zoos, circuses and even in private dwellings. This affects their behavior because they are not being kept in their natural environment.
