Cleaning Burrows

[Jujuuls]

So I was looking around Hamburger’s enclosure and noticed she’s been hoarding her food in her burrows! I know this is normal behaviour for them but I’ve noticed that there’s also poop mixed with it. She has a sand box for her to do her business in and she does use it but I guess sometimes she’s too lazy to get up Anyway, I was wondering what was the best way to clean her burrows without destroying her hard work? I don’t think I have to clean it anytime soon since she’s been with me for only 2 weeks but just wanted to know for the future.
