He didn't flood the tub, he sprayed it lightly. He said the pellets still kept their shape. I don't think you can compare the efficacy of the bedding in the first photo to his bedding that he only spraged lightly. If he says it's working, I think it would be great and maybe female rats can raise their pups on it? I'm buying some of this pretty soon so I'll get to experiement with it also myself.
