Wood to Avoid:

* Pine (in large quantities): Pine can be harmful in large quantities, so it's best to offer it in moderation or avoid it altogether.
* Cherry: Cherry wood can be toxic to guinea pigs.
* Oak: Oak contains tannins that can cause digestive problems.

Important Notes:
* Always ensure the wood is untreated, unpainted, and free from pesticides.
* Source your wood from a reliable source, ideally from a pet store or from trees known to be safe.
* Supervise your guinea pigs when they are gnawing on wood.
* Introduce new wood slowly, as some guinea pigs might be sensitive.
