I love these and more importantly my cats love these. They hold enough litter for multiple cats to use... I clean them every day and ever 6 weeks I replace the litter box with a new one. No orders and the box holds up well.
These litter boxes are the best. I throw them away when they get full. No cleaning required! The cats enjoy nice clean boxes too!
We were so bad about scrubbing the litter box clean. Now we never have to!
