Tonight I noticed my bearded dragons sand is stinky and its been a few months since I have changed it. I a ways scoop the poop out but it was smelly. I had some Zilla Walnut Shell substrate laying around and changed it. I have seen stories all over the net and even saw the photo of the disected bearded dragon with the walnut substrate in its gut. Do you think he will be okay for a day or two until I can get some new lizard carpet?? I never feed him directly on sand, always on a plate.
