Efficacy of fluralaner spot-on solution for the treatment of Ctenocephalides felis and Otodectes cynotis mixed infestation in naturally infested cats.

ABSTRACT

BACKGROUND: Cats can be infested with several ectoparasite species, especially Ctenocephalides felis and Otodectes cynotis. The aim of this study was to evaluate the efficacy of a single topical application of fluralaner against C. felis and O. cynotis natural infestation in stray (study 1) and owned (study 2) cats in central and southern Italy. RESULTS: The number of live fleas found on each cat on Day 0 ranged from 1 to more than 30 (arithmetic mean live flea count = 11.9 in study 1; 14.6 in study 2) while no live fleas were found on days 7 and 84 post topical application of fluralaner. The number of live mites found on each cat on Day 0 ranged from 1 to 42 (arithmetic mean live mite count = 6.4 in study 1; 8.9 in study 2) while no live mites were found on days 7 and 84 post topical application of fluralaner. CONCLUSIONS: Topical fluralaner completely eliminated fleas and ear mites from infested cats and was 100% effective against both parasites up to 84 days after treatment.
