They mainly use the main cage, but there are ushally a few poops but thats about it, they are sorta potty trained, but not completely. They dont spend a whole lot of time out on the carpet because all food, hay, water, and hideys are in side on the shavings, which helps control the poops and pee too, but in the morning and at night when they are super active and popcorning they go out there and run laps, they go out in the day sometimes but dont spend a lot of lime out there, the mainly lay in there hideys during the day. But if there is a pee spot I clean it with Vinegar but theres only been one in 3 days but if they start going out there more which I dont think they will but if they do ill put a shower curtain with a sheet or blanket over it down.
