Caixas de Armazenamento de Plástico, Recipiente de Armazenamento Empilhável com Fechos de Segurança e Tampa Preta, 32 Qt.

The deep pan gives my cat plenty of space to dig without flinging litter everywhere, and those rubber feet keep the box planted even when he does his post-bathroom zoomies. Cleaning is honestly a breeze now.

I was skeptical my 12-year-old cat would climb in, but the top entryway is wide enough that he figured it out in a day. The non-skid rubber feet are a nice touch too, the box stays put when he jumps out and flings litter everywhere.

My cat took to the top entry right away, and I've barely swept any stray litter off the floor since. The deep pan holds a lot, and the rubber feet keep it from sliding when she jumps out.
