LICE Louse infestation (Pediculosis), is uncommon in cats, These highly host-specific parasites, and are more common during the winter months. These tiny (1/10th of an inch or less), white, flattened, wingless creatures can be seen under a magnifying glass. They have six legs, and live on the skin, can be seen all over the body, and are equipped with either sucking or biting mouth parts. Although there are different types of lice that affect animals, the type that affects cats is Felicola subrostrata, which bites and feeds on skin debris. Since this condition is often associated with poor sanitary conditions or neglect, malnourished, debilitated cats who are unable to groom themselves are those usually affected. Infestation is caused by direct contact with an infected animal, or contact with the environment where an infested animal has been. Left untreated, other conditions may occur, such as Miliary Dermatitis. In the life cycle of lice, the female lays eggs (nits) on the cat, which are attached to the hair shaft. Once hatched, the adult lives its entire life reproducing and living on the cat, feeding on skin secretions and debris. Diagnosis Cats infested with lice, usually have dirty, matted, odorous fur. Lice have sharp claws, and cause intense irritation, which makes the cat ill-tempered. Lice can be seen under a magnifying glass, by looking under the matted fur. You will see the parasite or eggs glued to individual hairs of the cat. Other signs to look for are scaly skin, itchiness, or scabby skin. Treatment It is important to first have your veterinarian diagnose lice, however, since they live exclusively on the cat, they are easier to get rid of than some of the other external parasites, and it is only necessary to treat the cat; not its environment. However, if one cat is infested, it is necessary to treat any others in the household as well. Remove all matted hair and commence weekly topical treatment of a cat-safe flea/tick product for up five weeks will rid your cat of lice. Remember, these products are insecticides , and as such, should always be used with extreme caution. Advice from your veterinarian is suggested. References: The
