Soooo they're
not sweater boxes exactly... they are boxes I used my sophomore year of college as under the bed storage, from IKEA.
Consider using a large storage container or
sweater box as a litterbox.
We set them up in individual shoe or
sweater boxes, on clean bedding and with a water bowl.
Equip closet shelves with see - through plastic containers,
sweater boxes, stacking bins, and drawer units.
