The lioness has departed from her pride whilst carrying offspring. This behaviour is not uncommon among female lions, as they often seek solitude during the gestation period. The lioness will typically seek out a secluded area to give birth and care for her young. This behaviour is a natural instinct for the lioness, as it allows her to protect her offspring from potential threats and predators. It is important to note that the lioness will eventually return to her pride with her cubs, where they will be integrated into the group and raised collectively.
