Green Wood varnish/presever?

Hi Guys
Was wondering if you could help me please? I would like to find that bunny friendly green varnish/preserver thats used on some rabbit hutches- any idea of brand please? (Or blue may be nice!)

And what should be used inside to stop urine from soaking into the wood?
Thank you!

Hi there, I have just done my new hutch and run is a lovely colour called Willow by Cuprinol. Its animal friendly and comes in loads of colours, different shades of green and blue included. HTH
