We had a deck put in last summer and wanted to treat it to stop it rotting. We bought some decking oil after a friend recommended it, but wary of using it because of the cats. Looking at the safety data sheet, it looks quite scary - any experience, or safer alternatives? - I would rather use something like Linseed oil (assuming it is safe) and have to redo it more often, than risk harming the cats.
Any thoughts?
