Meerkats have developed several strategies to protect their colonies from predators. They work together in groups and take turns standing guard to watch for potential threats while the others forage for food. When a predator is spotted, the guard will sound the alarm by making a high-pitched noise to alert the group to take cover in nearby burrows or bushes. Meerkats also have a well-coordinated social structure that allows them to cooperate in defending against predators, with some individuals acting as sentinels while others protect the vulnerable members of the group, such as the young pups.
