Our Sure-Grip Grooming Perches are going to please you and your bird. These natural hardwood branches are covered with crushed walnut shells so they provide effective grooming for nails and beaks. Each perch has a comfortable textured grip that a bird will easily grasp. These are a wonderful lightweight alternative to cement perches that won't stress the cage bars. Being made of natural wood, no two perches are exactly the same and dimensions may vary.
