Learn all you can before making your choice. When deciding upon a cage lining material the first concern must be safety. The second is that it should enable you to see and monitor your bird's droppings. Safety Birds are intelligent and ingenious animals and many can find a way, no matter how hard we try to prevent it, to get at the bedding material in their cages. Unfortunately there are a number of products on the market today which, if ingested, are harmful to birds and can even cause death.
Most birds are quite messy.
The combination of dropped food, spilled water and bird poop is a rich environment for bacteria to flourish and is also an open invitation to flies, ants, mice and other small animals. Some bedding products promote growth of molds, fungi and bacteria and should never be used for bedding. Examinability Use a bedding product which can be easily examined. A change in your bird's droppings can be an indicator of illness so they should be examined each day. You want a product which will make it easy to see the constistency, color, volume, shape and number of the droppings.
