I put two hides in there. The one that is blue is a 5gal bucket that i stole from my dad lol.... shhhh but i put that underground at a tilt and then stuffed it with dirt and grass.
and the second one are rocks that i found on a trail i go on, i stacked them basically and she pretty much did the rest and made a nice den for herself under it it goes pretty deep and was amazed she did that lol.. gotta love Russians
