I recently previously got two 3 or 4 year old fuzzbutts. The previous owner only had the basement level in the 4-level cage and had bedding which they used as litter covering the whole floor. I have all the floors in and a litter box in the corner with blankets in the bottom, but they poop on the blankets too. The litter box is a hit or miss. Is litter training older ferrets harder? i am also getting a playpen with a bottom and don't want them pooping all over the floor.
