InSight Clean Cup Feed and Water Cup - Large™: A cup feeder with a difference -- a clear plastic shield keeps food and debris from falling outside the cage. If your parrot enjoys the occasional food fight, the shield and the cup placement a few inches into the cage, combine to solve the biggest problem reported by bird owners in all surveys...keeping the area around the cage clean. And because it's clear, parrots don't mind sticking their heads into it (unlike opaque shields). The Cup Feed and Water Cup Large™ is made from nylon and acrylic parts. Its unique washer system makes it a breeze to fit all size cages available. Plus, it's easy to clean. It screws into the horizontal and vertical bar cages to guaranty a secure fit.
