safe to make shelves with?

[TnkTaingTal]

I'm looking to make a new shelf in one of my cages. How can you tell if the wood is safe for them? They dont label them "untreated kiln-dried white pine"
I found select pine at lowes, but I don't know if it's kiln dried or if its white or radiata. I went to home depot and asked for untreated kiln-dried white pine and the guy gave me "common board" I looked it up and found that common board is typically whatever was available that day and that they don't guarantee the species. Anyone have more knowledge/advice on the subject? Can I use one of these or do you know where and what exactly I should look for?

Thank you!

Home depots KD pine is listed as 'select pine'. ('select' being a grade of wood). Of course if your uncertain, you can always use the poplar. I used that for years (and still do). Both woods should be found right near each other.
Id avoid common boards or anything glued together. And if im not sure, i dont chance it.
