Shake well. Spritz onto your cat, on a brush, or on your hand and pet into the cat's fur. Petting them in the opposite direction of the fur will allow the formula to get down close to the root of the fur. Use in the areas most heavily occupied by the fleas, such as the tail and down the back. This is an all natural spray that is safe for your feline. It should be done outside if possible, as it is a repellent and does not kill the fleas. Ingredients: Lavender, Lemon Verbena, Rosemary, Distilled Water, Grain alcohol. 4 oz spray bottle.
