Open-top boxes keep the cat out of any enclosure: the litter bowl tilts or rotates beneath an open rim, so there is no entry to squeeze through and nothing that closes over the cat. They suit large breeds and cats that refuse hooded boxes. They let more litter scatter, and several makers here rate them for the heaviest cats in the catalog.
