Not to worry - a little blood here with the neutering of a large cat (tiger). This humane method is often used in animal husbandry. In this case the tiger has fathered a number of cubs but the zoo recognized there is a necessary limit to the captive tiger population because abuses can occur. With the veterinarian's help the zoo does its part to restrict tiger population. The video is educational from a biology point of view and the veterinarian is quite informative. This tiger is healthy and enjoying a good environment at his zoo home.
