You probably couldn't have picked a worse substrate. It is well known that cedar is toxic to most reptiles. I would STRONGLY urge you to chuck everything, scrub the entire cage down and hope that you didn't already do permanent harm to your burms (I would even find a way to get some pure oxygen pumped into their system if that's possible). For now, I would just keep them on newspaper until you know that they are okay. After that, either stick with newspaper, or, use Aspen if you prefer a wood type of bedding. Hope you heed this warning.

>>I have two burms and have just started using an organic cedar mulch. I have used cypress before but now wit the 6' x 6' cage I started using ceadr it seems like the same texture and hold moisture as good but smells better and is $4 for 2 cu. ft. Rater than $30 for 1cu.ft. Has anyone used this before?
