The new alternative to monthly topicals, flea and tick control that lasts up to 8 months. Seresto, from the makers of Advantage II and K9 Advantix II.
Approx. 15" L.
* Bathing or swimming more than once a month could result in a shorter active period for the collar.
I've got 3 cats that are outside during the daytime/inside at night. They lasted every bit of 8 months and no fleas! Very satisfied with this product.
