I bought the materials tonight to cover the back of the cage. The wood I believe is called "Lauan?"(maybe) and is approximately 1/4" thick. It is strong but lightweight. The description says it is water-resistant, but I figured that it wouldn't be resistant enough to rattie piddle. I found some polyurethane waterproofing and was wondering if anyone knew its toxicity on rodents. If it is toxic at all... I know alot of people use it to coat the insides of wooden snake cages. I know it is toxic in its liquid form, but what about after it has been applied to wood and has been allowed to off-gas for 48 hours or so? I doubt they will be chewing on it, since they aren't big chewers(except Harry...Dufus), and I doubt they could get a grip on it with their teeth since it will be the flat back.

If I can't use this stuff, then I will just go buy some more of the melamine-coated stuff. If anyone has any experience with this stuff, I would love some feedback. Thanks a bunch
