Domestic cats may be called 'house cats' when kept as indoor pets.[7] They are one of the most popular pets in the world. Humans keep them for hunting mice and rats, and as friends. There are also farm cats, which keep mice and rats away; and feral cats, which are domestic cats that live away from humans.[8] In 2021, there were about 220 million pet cats and 480 million feral cats in the world.[9][10][11]
There are about 92 breeds of cat.[12] Domestic cats are found in shorthair, longhair, and hairless breeds. Cats which are not specific breeds can be referred to as 'domestic shorthair' (DSH) or 'domestic longhair' (DLH).
