I have had my little girl for about 9 days and when I got her they had her on aspen bedding. She does sometime eat it and havent seen a problem with her passing it, I was wondering how deep the substrate should be. She tends to dig all the way to the bottom of her enclosure and lays on the glass. I have a log house in with her but I have yet to see her go in it. Should I change the substrate or just add more so she can dig in some more
