Dig Box Alternatives

[resamille]

Does anyone have some good dig box ideas that don't involve substrate? I'm trying to avoid substrate as I have carpet and expect it will get tracked around everywhere and be impossible to clean. I did try out making an alternative using hay, which seemed to work okay for my last beardie, but it's difficult to clean up if certain reptiles poop in it. I've been thinking maybe some cloth strips might work, but I'm a bit worried about stuck claws. Suggestions appreciated!

Some people have used cloth strips but one owner said their beardie tried to eat a piece so there's a risk of getting impacted. If you don't want dirt tracked on to your carpet can you just check Lio's feet before you let him/her out ?
