Pawbreakers are made with 100% natural ingredients, sourced and produced in the U.S.A with veterinary approval. The secret lies in the use of beeswax, a natural substance that has been used for centuries, to lock in an impressive 1/2 ounce of fresh, aromatic catnip into a 1.25-inch ball. Each time your cat bites or scratches the Pawbreaker, the delicious aroma is released, providing a fresh and irresistible experience. And don't worry about your cat's teeth - Pawbreakers are easily chewable, digestible, and safe for your furry friend. Pawbreakers were meticulously created and evaluated for optimal size, shape, and weight to stimulate your cat's instincts and provide long-lasting fun and exercise. We recommend indulging your cat every 2-4 weeks for maximum enjoyment and benefits. We highly suggest one Pawbreakers Bonkas per cat.
