Can I use plywood to build a nesting box for my rabbit or is that unsafe?
I think it may possibly be unsafe if it splinters.
I raised rabbits and had over 400 as long as you don't leave the Box in the cage they rarely chew it. I think I can help you out with anything rabbit wise. Wood shavings are better than straw for bedding straw gives them ear mites.
It should be safe my friend used it for there's before
