Are there any hardwoods that are toxic for gliders?
My fiance bought some hardwood dowels to make some climbing toys for our babies but it does not say what wood it is actually made of, just that it is hardwood.

I'm really not sure about the safety of hardwoods but a google search might be helpful. Some woods are treated so of course those would be a concern. Hopefully someone with more knowledge on this subject will be able to offer more insight.
