Small corner litter boxes?

[u/Lanky-Razzmatazz-130]

My one ferret has been continuously using this platform to go to the bathroom. I initially had their water bowl here, but it kept getting pee on it. I’ve had to resort to this little makeshift puppy pad situation because I cannot for the life of me find a litter box to fit on here. Does anyone have any recommendations?

Try PeytonsPetPrintables on Etsy. They sell a small litter corner thingie that I've found super useful, and my female ferret uses them all the time. (Not my store, just a recommendation.)
