Program for cats is a monthly treatment for ridding flea infestations. It acts on the flea life stages and kills larvae and pupae thus eliminating all chances of flea multiplication. A fast acting formula, Program tablets and oral suspensions kill fleas on cats within 24-48 hours and remain effective for one month. Information: Manufactured by Novartis, Program tablets and suspension for cats are given orally. Lufenuron, the active ingredient acts from within the cat’s body by circulating in the bloodstream of the feline. It attacks flea eggs and breaks its life cycle thus preventing flea re-infestations. To get the best benefits, it should be administered with food so that the ingredients are completely absorbed. This long-term flea control treatment inhibits complete flea infestations when administered two months before fleas become active and continued for six months. Just give one dose on a monthly basis and make your cat flea free.
