Meerkats are primarily insectivores, but also eat lizards, snakes, scorpions, spiders, plants, eggs, small mammals, millipedes, centipedes and, more rarely, small birds.
They are partially immune to certain venoms; they are immune to the very strong venom of the scorpions of the Kalahari, unlike humans. They have no excess body fat stores, so foraging for food is a daily need.
Meerkats forage in a group with one “sentry” on guard watching for predators while the others search for food. Sentry duty is usually approximately an hour long.
