Good afternoon. I'd like to hear y'all's opinions about using MCA (not CCA) pressure treated lumber to build a cat tree.
If you don't know, this is a cat tree: Google Images
My cats are not chewers. There will be no exposed wood; everything will be carpeted or wrapped in jute.
This is the new MCA stuff (Yellawood, ProWood) not the old CCA stuff.
Also, assuming this is safe, would galvanized fasteners be recommended or could bright common be used? It's indoors so I don't think there'd be enough moisture to catalyze the copper to attack the steel. But I could be wrong. Do framers use galvanized to attach PT bottom plates to non-PT framing when finishing a basement?
Thanks for your opinions.
