Hello

I am currently setting up a terrarium for a whites tree frog. And I acquired a half log from a friend and was wondering if certain types of woods could harm my new frog(I don't have him yet). I think the half log is cedar. I baked it at 200 degrees for an hour to kill any mold and it had a perfume like smell to the wood so I thought it was cedar. Anyways any helpful info would rock! Thanks in advance!
