Zodiac Flea & Tick Collar for Cats with Unique "Breakaway" Design Protects for "8" Months

One size fits all collar kills fleas and flea eggs for eight months and kills ticks, including those that carry lyme disease, for six months. Unique breakaway feature minimizes the risk of injury to your cat. This collar is designed to stretch under the weight of an average sized adult cat. It helps the cat to free itself (breakaway) if the collar gets snagged on a fixed object, making it especially great for outdoor cats. Offers continuous action even when wet.
