Better and more worse-tasting than ever, Yuk-2e’s wildly successful formula has been embellished with two additional bitterants to make it the most potent taste deterrent yet! Developed by veterinarians, Yuk-2e is a non-toxic but terrible-tasting gel that contains the highest level of the most bitter substance known to the medical community. Yuk-2e can be applied to areas around wounds or lesions to help prevent further injury by the animal. It is also used to prevent the tearing of bandages, casts or catheters as well as chronic licking. It's also used for puppy proofing and furniture protection.
