Adopting a bunch of cats can be fun but keeping their litter box clean and odor-free is a whole other issue. The Janar Litter Box aims to solve that problem. It not only saves you time cleaning the waste but has spray-type-sterilization & deodorization functions.
The Janar Sphere looks quite elegant. Its rotary filter plate lets you sift litter quickly. The door sill plate reduces litter tracking.
