Wood sealer in the USA that is safe I think

[AmityvilleHams]

While one portion of it may be safe,the other parts were still not specified by the manufacturer and therefore they'd not be okay.If anything,I'd be more worried about those parts.

We already know that clay isn't great for hamsters to ingest,so I'd say a product containing clay shouldn't be used either.There are safer natural DIY options for wood seals,and these options are far superior to questionable products.
