Q
I had the same problem when I was building my cage...
In Germany, we use that seethrough
varnish you use on childrens wooden toys. It is safe to chew on and everything, because little kids tend to bite into everything they can get hold of. Now, I went into all local DIY shops including B&Q, and they didnt have anything like that. They knew what I meant, but they never heard of it being sold here :o
In the end, I used
Ronseal Quick Drying Woodstain, my nearest DIY shop rang them up for me and asked if its safe to use for pets.
They said yes, so I used it... well it sort of comes down to "do I believe everything they say or not"..
There is also a cheaper option of
Woodstain from B&Qs own brand, which even says on the tub "pet friendly" or something. And a shop assistant told me she has rabbits and painted her hutches with it, she never had problems..
But if you really want to go for a proper varnish, the one for childrens wooden toys is what you should look out for. Tell me if you found any, please! Because i would love to use it again, but its too expensive to ship over here from Germany
Too heavy...
