Ceva Animal Health has launched its second flea killer for cats with the introduction of Catego. The monthly topical drug, which also fights ticks, contains what the Lenexa, Kan., company called a unique formulation: the active ingredients dinotefuran, fipronil and pyriproxyfen. Catego joins Vectra as one of Ceva’s two flea preventives for cats. Both products are formulated to kill fleas within six hours, or twice as fast as competing products Frontline Plus and Advantage II, according to Ceva. The new preventive comes in three- and six-dose packages, and it is indicated for use in cats over 8 weeks old and weighing more than 1.5 pounds. As a tick preventive, Catego is formulated to kill four species: the Brown dog tick (Rhipicephalus sanguineus), American dog tick (Dermacentor variabilis), Lone Star tick (Amblyomma americanum) and Deer tick (Ixodes scapularis). Ceva is selling Catego through distributors MWI Animal Health, Penn Vet Supply and First Vet Supply.
