For kittens, World’s Best Cat Litter worked surprisingly well for us. I was worried about corn litter because my kitten tried to taste everything, but she lost interest quickly. The lighter weight made cleanup easy, and clumps formed fast. Dust was minimal, which mattered in a small space. Once she grew, we transitioned to the multi-cat version without issues. Between that and feeding Nutra Nuggets kitten food early on, training felt pretty smooth overall.
