There is only one species of feline lice: Felicola subrostrata, also called feline chewing louse. This louse will get up to 1.3 mm long and is characterized by its triangular head. As a biting lice, it is quite peaceful as it eats skin flakes, etc. This does not usually bother the cat. However, biting lice are active, and if there are many of them it bothers the cat. The feline chewing lice are uncommon in domestic, well-nourished cats and more common in wild cats, especially during the winter. Fighting is rarely necessary, however, if necessary, the same treatments as used on canine lice can be applied. Be aware that cats may be intolerant of some treatments.
