My little dog is on a diuretic due to heart diseases and so having a lot of accidents around the house, so I made an indoor outdoor potty. this is just a plastic deep pan, with soil, and turf of grass on top which was cut from a rolled piece. I knew the little ferret would probably enjoy this too, but she has played with this more than any other dig box, in the past she has had dig boxes with soil, rice, shredded paper etc which she has enjoyed but with this turf of grass she dig at it for ages!! Might be just a her thing but worth a try if you are looking for a new thing to keep your fuzzies occupied 😊 I'll insert a photo below! Have fun!
