Giant bamboos are the largest members of the grass family.
In bamboo, the internodal regions of the stem are usually hollow and the vascular bundles in the cross section.
They are scattered throughout the stem instead of in a cylindrical arrangement.
The dicotyledonous woody xylem is also absent.
The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos.
These are to be columnar rather than tapering.
Most bamboo are native to warm and moist tropical and warm temperate climates.
However, many species are found in diverse climates, from hot tropical regions to cool mountainous regions and highland cloud forests.
Timber is harvested from both cultivated and wild stands, and some of the larger bamboos, particularly species in the genus Phyllostachys, are known as “timber bamboos”.
Bamboo is used for a whole number of things due to its versatility from building structures to cooking utensils. (source wikipedia)
So can hamsters eat bamboo at all to chew on so that their teeth can have something to grind down?
Yes they can eat bamboo, as long as it isn’t bamboo that has been brought in from the wild.
It may have bacteria on it that maybe harmful for them hamster.
It is better to give them bamboo which has been internally stored.
They will find it very good for gnawing their teeth on and keeping them from growing longer than they need them to be.
