Untreated timber for rabbit?

[chloe leung]

Hi (new member here),
I have an outdoor rabbit and I noticed he likes chewing on sticks (he also loves tunnels/burrows). I want to give him an outdoor toy that he'll be able to play with even when it rains. I want to make a untreated timber tunnel for my rabbit to chew on, would the wood be toxic for him?

That depends on the type of wood. Check sites for what branches are safe for rabbits.

Here's one source (scroll down on link for trees, etc):
