We apologize but we for some reason have not loaded the usage directions for this product into our system since it is new to our inventory. You can reach the manufacturer of the Greenway Formula 7 repellent at 855-746-7929 to find out usage instructions. That being said, please keep in mind that if your cats repeatedly get flea infestations on them, you need to make sure you are treating the home as well as the yard with a flea control product to keep fleas from being so prevalent in your yard for them to bring in on their bodies. Using something like our Indoor/Outdoor flea kit is a safe and effective way to keep the fleas, ticks and other pests in the yard away so your pets can enjoy it without the fear of severe repeated infestations.
