BirdCageLiners - Small Cages - Pick Your Size - 60 Pre-Cut Sheets (13 x 14.5) 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. Our forty-pound paper is ideal for your smaller bird species. We use raw Kraft paper made in U.S. Paper Mills. We do not use inks, dyes, wax or any other contaminants. Our liners are delivered rolled in single precut sheets that 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. Your bird has an extremely delicate respiratory system and must not be exposed to contaminants such as wax, inks or dyes. There are many articles written about the preferred birdcage liner, they all state plain paper! Our recommendations are 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. You can easily access our entire line of liners by typing birdcageliners (all together no spaces) in the Amazon Search Bar. Please measure the inside of the cage pan, not the outside of the cage for proper fitment.
