Twister?, a health and exercise perch, provides a variable diameter and shape that allows a new contact point every time the bird regrips the perch. Common round perches keep pressure points on the same spots on a bird?s feet, even when the bird moves on the perch. This unique perch imitates natural perching situations, supplying a variety of positions, heights, and angles with every new stance. The bird enjoys improved strength and flexibility. Its patented surface is guaranteed to automatically trim the bird?s nails. A bird spends its life on its feet. Polly’s Twister? furnishes more natural, more comfortable perching conditions.
