The Kagesan Sanded Sheets come as a pack of 8 and fit into bird cages, providing a false floor which can be easily replaced when dirty. The sizes provided can be easily cut down smaller to fit, as they are made of sandpaper. Just replace the sanded sheets once or twice a week and you can ensure that your bird has a happy, clean cage to fly around in. The sanded sheets are great for using in cages with Budgies, Canaries, Cockatiels, Finches and Parrots.
