This flea collar offers an easy, topical solution to the pesky problem of cat fleas - and protects up to 6 months. Sentry PurrScriptions PLUS Flea Collar for Cats uses ingredients including propoxur, phenothrin, and pyriproxyfen to kill adult fleas, flea eggs and flea larvae. Since 90% of a flea infestation can exist in those pre-adult forms of the flea (egg, larvae, pupae), this collar protects your pet against reinfestations for up to 6 months. This cat flea solution requires fewer applications than monthly topical products. Made in USA. 0.5 oz (14 g) collar.
