Description: I was inspired by other posts about cat litters so I decided to hack one for my living room.
These are two besta cabinets, both 60cm width and 40 cm deep; but one is 40cm high and the other one is 60cm so I could put it under the stairs.
I just cut three holes in the sides of the cabinets as shown below.
Inside I put a little carpet in the first cabinet to keep the sand inside and avoid it to go everywhere.
In the second “room” I built the litter box with a coroplast sheet. I made it the same dimensions as the interior of cabinet.
Below the scheme to cut and fold the coroplast sheet
After you cut and fold it, just use a stapler o a strong glue to keep together.
