Coastal's Lazer Brite Reflective Adjustable Breakaway Cat Collar features reflective material to keep your cat safe at night. Lazer Brite Reflective Cat Collars are made from the same reflective material used by safety professionals and are visible up to 600 feet away. The buckle is designed to release if a cat's collar gets caught, allowing it to slip free. Not for use with leash or tie-out.
