"Car trash can. Reuse cascade box." - This is great, you can do it with old kitty litter containers, empty sani-wipe containers, whatever you like! Love the idea of lining it with an attractive fabric, so smart!
Cat beds furniture. Top has cushioned area for kitty to lounge. Hide her litter box in the center that has a flip door. Keep cat toys, litter scoops and meal accessories in the additional storage on the sides. A unique cat bed!
