Open-Top vs Enclosed Globe -- Which Is Better for Your Cat?

Self-cleaning litter boxes come in two primary designs. Enclosed globes (like the Litter-Robot) fully surround the cat during use, which maximizes odor containment but can cause anxiety in cats that dislike small spaces or require more room. Open-top boxes like the Neakasa M1 Plus look more like a standard litter box -- the cat steps in from the top, does their business, and steps out. The automated cleaning arm or rotating mechanism handles waste after. Open-top designs typically work better for large cats, senior cats with mobility issues, and cats transitioning from traditional boxes for the first time.
