Introducing the FreezWheel - a enrichment toy with a wheel-shaped design featuring multiple compartments, this is great for adding a variety of fillers, and enhancing their snack experience. Its innovative design is made to hold a variety of fillers, from liquids to solid treats, ensuring hours of engaging fun for your furry friend. Made from 100% Natural Rubber, the FreezWheel is non-toxic, biodegradable, and (I recommend top rack) dishwasher-safe. Available in orange, navy, and purple. One size.
