Advantage Seresto Cat & Kitten Flea Collar is a unique flea collar that provides up to 8 months of protection.

Made of a novel blend of materials, it releases its active ingredients in small doses giving your cat a safe and controlled barrier.

It can be worn along with your cat’s normal collar and can be adjusted to fit any cat. The Seresto collar works through Sustained Release Technology – the active ingredients are released continuously from the collar in low concentrations; it then diffuses on the pet’s skin/coat, through the natural skin lipid layer.
