Using these multi - colored cotton bird perches is super easy. Just install them in your bird's cage at different levels to create an exciting environment. When choosing a size, think about the size of your bird. Smaller birds may prefer the small perches, while larger ones will be more comfortable on the large ones. As for maintenance, check the perches regularly for signs of wear and tear. If they get dirty, you can gently wash them with mild soap and water, then let them dry completely before putting them back in the cage. Keep in mind that although these perches are flexible, don't bend them too sharply to avoid damage.
