Lice occur sporadically in cats and are usually the result of a nest infection. They are transmitted by direct contact with infected animals and through contaminated combs and brushes. Apart from the cat’s body, lice only stay alive for a few days. They can just be seen with the naked eye. Yellowish nits (eggs) on the hair of the cat are characteristic of a lice infection. The nits should not be confused with skin flakes. For the control of lice, the same means can be used for the control of fleas. Both the animal itself and the environment should be treated. It is also essential to pay extra attention to hygiene. Combs and brushes should be cleaned and disinfected regularly.
