Wolf packs are established according to a strict hierarchy, with a dominant alpha male at the top and alpha female not far behind. Usually this male and female are the only animals of the pack to breed. Packs consist of between five and ten animals – usually offspring from several years. All of a pack’s adults help to care for young pups by bringing them food and watching them while others hunt.

Lionesses are caring mothers who will even take care of a neglected cub, allowing him/her to suckle and giving them a chance to survive. Two or more lionesses in a group tend to give birth around the same time, and the cubs are raised together. Cubs are extremely playful.
