Using these Tweeters Colorful Pumice Pedicure Perches is a breeze. First, use the secure metal hardware to attach the perch to your bird's cage bars. Make sure it's firmly fixed so your bird can perch on it safely. Your bird will naturally start using it to trim its nails and peck at the perch to clean and condition its beak. There aren't many special care instructions. Just keep an eye on the perch regularly. If it gets dirty, you can simply wash it with mild soap and water, then let it dry completely before putting it back in the cage. As for the size, choose the one that suits your bird best. Smaller birds may be more comfortable on the small perch, while larger birds will benefit from the medium - sized one. Remember, the color you receive may not be the exact one you're picturing, but they're all bright and colorful to make your bird's cage look great.
