Fennecs are social animals that live in groups of around ten individuals. They live in burrows during the day and do their hunting at night. Fennecs are opportunistic omnivores, feeding on everything from plants, to insects, to eggs, to small rodents and birds. The Fennec's main non-human predators are large(ish) cats and birds.
Not much is known about their wild status, and they are listed by IUCN as being of Least Concern due to deficient data and unavailable information. You apparently can own Fennecs as pets legally, but keep in mind that they are burrowing, nocturnal, wild animals. I wouldn't recommend it.
