Rosewood Boredom Breaker 6 Pack Mini Sisal Carrots are small sisal and dried corn leaf carrots – replacements designed for use with the small pet carrot play patch. Of course, the carrots can be used on their own too, great for bunnies and guinea pigs to flip, fling and fetch. Made of safe, lightweight materials and filled with beans to add a rattle as it rolls, the sisal surface is perfect for pets to pick up their toy!
