Super Pet Chinchilla Leap-N-Ledge www.petsmart.com - $5.99 Product Description: The Leap-N-Ledge is a terrific way to encourage your small animal pet to exercise. Place several at different levels in the cage to stimulate leaping behavior. It is made of natural, untreated wood, so it's also a good outlet to indulge instinctive chewing behaviors. And it gives perching pets a place to comfortably hang out. Your chinchilla, sugar glider or pet rat will thank you for it! RattyRat's Review: These wooden ledges work great. They have a secure fit, and our rats love to perch and climb on them. We arranged them like stairs going up to their hammock. The only down side is that they are wood, so they are more difficult to clean.
