Pet Head Cat Knot Detangler has been developed to help get rid of nasty, uncomfortable tangles quickly and easily. Spray a generous amount onto the matted area and massage it in thoroughly; lightly pull apart and separate the hair and then use a brush to patiently work the knot loose. Scented with a pleasant watermelon fragrance, the spray can be left in to keep the coat soft, shiny and tangle-free. Use as needed.
