Sandpaper is a practical alternative to bird sand. A sheet of sandpaper is simply placed on the bottom of the cage and regularly replaced to keep the cage floor clean and hygienic. Additionally, the sandpaper contains valuable minerals, calcium, and ground seashells. These ingredients enhance the well-being of the birds and promote digestion. By pecking at the sand grains and walking on the sandpaper, the beak and claws are maintained in their natural form. Ideal for canaries, budgerigars, and all other caged birds.
