Avian Select Natural Wood Bird Perches www.petco.com - $6.49 (1" diameter) Product Description: Real wood perch naturally exercises your bird's feet and legs. Securely attaches to cage with built-in bolt and wing nut. RattyRat's Review: Our rats enjoyed perching on this wooden perch, and the natural texture made it easier for our rats to grip on to it. However we didn't find this perch to be as versatile as products like the leap-n-ledge and cable comfy rope perches. Also, because only one side of it attaches to the cage, it gets real wobbly when a rat walks out to the end of it. Mostly our rats would stay at the base of it. Not to mention it is wood and thusly harder to clean.
