Advertisement I am doing a mixture of 60% sand, and 30% clay. Its been drying for like 4 days now I think. And Ive noticed like, once the top layer gets dry, it can no longer hold a burrow, it turns into normal sand agian. Am i not suppose to dry out the sand completely? Because there is no water at all anymore, its just a little bit damp after about 3-4 inches into it (my substrate is around a foot deep), but not really wet. I know Desert hairies can get mycosis really easy, so i dont want to put it in there without being 100% sure it wont get mycosis, but at the same time, i want him to be able to burrow, hence why im doing this set up. What do i do?
