There are benzoic, oxalic and plicatic acids in pine and cedar. A lot of it
is given off, particularly with cedar, in off-gassing. Oak gives you tanic
and acetic acids.
All woods contain resins and some contain a combo that is toxic to animals.
Oak, along with cherry and black walnut contain those types of resins which
is why they aren't used as shavings for animals.
