Mini Preening Block is the perfect toy for medium sized birds to chew and preen! The combination of wood, and dyed sisal provide a multitude and colors and textures that will engage birds for hours. We only use natural food dye to color our products, so birds can have a safe and fun time! Exercise caution around birds with overgrown nails, as the nails can get caught in the sisal. We also offer the Large Sisal Preening Pole for larger birds.
