The African wild cat is not endangered at 2016. It is categorised as “Least Concern” (see chart below) in the scale of categories concerned the survival of species by the IUCN Red List. Obviously “least concern” means what it says namely that the scientists are, relatively speaking, the least concerned about the survival of the wild cat in comparison to other species.
See IUCN Red List for cats. Note: IUCN Red List categories change over time as populations sizes of species usually decrease resulting in a more critical category being assigned to a species. Personally, I’d suspect that lots of African wild cats are semi-domesticated in Africa or, more importantly, have interbred with domestic cats (creating non-purebred, hybrid wildcats) thereby reducing its population size dramatically by stealth.
