Penn-Plax's trimmer perch is a designed variable size perch which will trim your bird's nail and beak naturally while promoting healthier feet and leg muscles. Because birds spend most of their lives on their feet, problems can develop if they're confined to perches of a single thickness and shape. The Trimmer Perch are variable size which allows your pet bird to change and choose the thickness and shape for the most comfortable fit. Assorted Colors.
Dimensions: 5" x 1/2" Diameter (recommeded for Parrotlets, Finches, Canaries)
