Well if it smells like a ceder chest it's probably pretty toxic. The reason ceder used to be so popular for furniture (especially storage chests, armours or drawers) is because it contains a natural insecticide that will kill clothing moths and other fabric munching bugs. I used to use it a lot on rodent cages and never really noticed a problem either but when I got this carpet python she had some really bad neurological issues (head flipping around all over the place, she could barely eat) and the cage she came in contained a deep layer of ceder chips. All the reseach I could find pointed at that being the problem. After about 8 years in my care she's much better, but still has a bit of a head quaver.
