These hairs, which have numerous nerve endings at their base, are located above the eyes, on the cheeks, on the muzzle, and on their chin, as well as on the backs of the legs. The hairs on the muzzle, known as mystacial whiskers, are the most developed. These whiskers are mobile, and are used not only for detection, but for showing mood. The whiskers can clearly be seen on this marbled cat. Fur is typically dense and short, and provides insulation from the elements.
Cats have four types of hairs covering their body.
The thickest are the whiskers, mentioned above. Second thickest are special sensory hairs found all over the body that are longer than the rest of the fur. These hairs are sparse, and found evenly all over the cats body about every few inches or so, and the purpose of these hairs is the same as whiskers, only for the body. Third thickest and second numerous are the guard hairs, which are numerous and dense and protect the body from moisture and particles. The finest and most numerous hairs are the soft undercoat.
