Grannick's Bitter Apple Spray - The Original Taste Deterrent for Dogs and CatsBitter Apple is the oldest and most recognized taste deterrent spray. It is safe to use directly on the pets to discourage fur biting and licking, and can also be used on furniture, cords, clothing, or anything else you don't want your pets to bite. Ingesting won't harm the pet, but it has a horrible taste that makes cats and dogs not want to bite or chew something a second time. Also safe to use on plants to deter pets from eating them. 8oz
