BirdCageLiners - Small Cages - Pick-Your-Size - 150 Count - 40 Pound Paper/No Wax If you purchase one cage accessory, make it our cage liners. They will simplify your cage cleaning and promote a clean and healthy environment for your birds. We carry forty, sixty-pound paper liners and Poly Coated paper liners. We use raw Kraft paper made in U.S. Paper Mills. Our paper has no inks, dyes, wax or any other contaminants. Liners are delivered rolled and will lay flat without creases. Keeping your birdcage clean is the most effective way to prevent illness. Our paper is made from the same material paper bags are made out of and are light brown in color; the color makes inspecting bird droppings much easier. Our Poly Coated Papers are white paper with a very thin poly coating and guaranteed to not leak through. Our papers are all made in U.S. Paper Mills and have no inks, gravel, grit, dyes nor wax. Birds have an extremely delicate respiratory system and must not be exposed to contaminants such as wax. There are many articles written about the preferred birdcage liner, they all state plain paper. Our liners are delivered in rolled pre-cut sheets that will lay flat without creases. Our recommendations based on our experience and years of customer feedback. 40 Pound paper is recommended for small birds (finches, canaries, parakeets etc.) 60 Pound paper is recommended for medium size birds like Amazon Greys, Quaker Parrots, conures etc. Poly coated paper is recommended for larger birds like Macaws, Yellow Naped Amazon, Cockatoos etc. Please measure the inside of the cage pan, not the outside of the cage for proper fitment. You can easily access our entire liner line by typing birdcage liners (all together no spaces) in the Amazon Search Bar.
