This is all over the bottom of Diego's cage. I'm not sure if when I normally wipe down the bottom of his cage, after mister is done for the night, that I may have missed it before. I have no Idea what it could be. Pretty sure it isn't dusting power but maybe. They are like little oval shaped balls, very tiny in size maybe the size of a sesame seed or a tad smaller & the same shape too. Anyone have any idea what this could be? Thanks!!!
