Fooey! Gel is so disgustingly bitter, we actually have a registered trademark to say it’s “the most bitter stuff on earth!™” When used in conjunction with recommended training methods, Fooey! stops dangerous and destructive behaviours such as: unwanted chewing, licking, biting, ingesting and more. Our new gel formula and sponge-tip applicator conveniently allows the pet parent to apply product with less-mess and more accuracy. Great for doors, crown molding, furniture legs, dangerous plants – and even on the pet (hot spots & surgical wounds).
