Treat your guinea pig to a crunchy, long-lasting baked treat stick made with whole grains and wild berries, with a tasty berry and honey glaze. Vitakraft Crunch Sticks dont just taste good: they also promote important chewing needed to wear down guinea pigs always-growing teeth for optimum dental health. The triple-baked layers make this treat last longer, with a natural wood chew center that provides hours of chewing fun long after the treat part is gone!
