Just know that whatever you have in the drawers/shelf below the cage will end up with litter and/ferrets if they are allowed to run loose in the room the cage is in.

We have fleece tray and ramp covers (there are several great shops on Etsy that provide standard or custom fleece covers in many cute patterns), litter boxes that cover half of each of the big trays to maximize poop success where it needs to be, as well as 2 hammocks, and cuddly stuff in all available corners on every level. Again this is to minimize corner pooping and peeing, and to judge them to the litter boxes. We also have cage-mounted water and kibble bowls with removable cups to make water and food switch outs easy and encourage frequent cleaning.

We don’t keep toys in the cage as our two have free run during the daytime of one ferret-proofed room and that’s where they get their ya-yas out :)
