It is particularly strong and resists most bird`s chewing attempts indefinitely. The natural shapes help to exercise your bird`s feet and prevent sores.
Although Manzanita can split when drying like any wood, this is not a fault, merely an indicator of the hardness, your Parrot certainly won`t mind.
Be sure to provide plenty of other material for your bird to chew though!
Bolt at one end to fit any cage.
