I've been trying to find an answer to this, but since I haven't I figured that I may as well come ask myself.

My ball is a pretty big girl, and it's getting to the point that it's kind of difficult to find suitable hides for her anymore. A lot of the ones available in local stores seem to be meant for smaller snakes, and the ones that are big enough don't have a large enough entrance for the thickest part of her body. Recently, she outgrew her log hide, so I've been trying to find a good replacement.

I found a hollow section from a birch tree and was wondering if this would be a safe option for her. When I tried baking it to remove any possibly harmful things, a few areas began to release sap. I haven't been able to find anything indicating that birch sap is toxic to snakes, but I'm not willing to take the chance until I know.

Any suggestions or information would be wonderful, thanks!
