Purina Tidy Cats large hooded litter box (https://www.amazon.com/gp/product/B0776R7F84/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1) with scoop, many pad refills (https://www.amazon.com/gp/product/B07K8RWX12/ref=ppx_od_dt_b_asin_title_s01?ie=UTF8&psc=1), and remainder of bag of Breeze litter pellets. Can also use with pine cat litter! Great system and works well, but am switching to a larger box for my two adult cats.
