## Features

- SO DISGUSTINGLY BITTER – Fooey! Spray is so disgustingly bitter, we actually have a registered trademark to say it’s “the most bitter stuff on earth!” The taste comes from grapefruit skin extract and the herb known as “The King of Bitters.” These all-natural active ingredients deliver a safe, effective and powerful deterrent to destructive chewing, biting and licking behaviors.
- TRAINING AID – Use Fooey! in conjunction with training methods to keep pets from licking, biting, chewing and destroying anything they might like to go after in your home. Remember to reward your pet for good behavior and they will continue to practice their good behavior.
- SAFE FOR YOUR PET AND HOME – Alcohol-, fragrance-, odor- and dye-free, the neutral pH spray is non-flammable, non-acidic and non-caustic. It is safe for furniture, walls, shoes, clothing and harmful plants, and even safe to use directly on your pet’s skin to discourage gnawing and licking.
- PROTECT YOUR GARDEN – Use Fooey! outdoors to shut down the 24-hour garden buffet and prevent deer, rabbits, woodchucks and other vermin from eating your plants and flowers. Save time, money and frustration!
- PREMIUM PRODUCTS FOR PREMIUM PETS – SynergyLab’s Fooey! training products are created with premium ingredients but available at a price that pet parents can afford. We know your dogs are more than just pets, because we are pet parents too.
