Adams Plus Flea & Tick Collar for Cats helps prevent infestations by killing fleas and ticks for up to 7 months. Our one-size-fits-all flea and tick collar ensures you are receiving top-of-the-line flea and tick treatment for small, medium, and large cats alike. This collar is water-resistant, and does not need to be removed if it becomes wet. This collar can also be worn with a regular collar. The Breakaway collar features an easy release snap which allows the collar to come undone if snagged on a branch, furniture, or other objects in your cat's environment. Adams Plus Flea & Tick Collar For Cats is an odorless, non-greasy alternative to topical treatments to kill fleas that may cause flea allergy dermatitis, flea bite anemia, and/or may transmit tapeworm. With 5% of fleas living on your cat and the remaining 95% living in your home or yard, it is important to also address the infestations that can be occurring in your home and yard. Adams products are designed to provide you with the power to prevent pests on every front.
