Alternatives to the Whisker Litter-Robot 4

Buying advice: cat litter boxes

  1. Bigger is almost always better. Many standard boxes are too small for large cats, so storage tubs are a common workaround.
  2. Covers contain litter scatter and hide the view, but trap odor inside, which some cats dislike. Try an open box first if your cat is hesitant.
  3. Kittens and senior cats with stiff joints need a low entry. Top-entry boxes reduce tracking but are hard for older cats.
  4. Automatic boxes save daily scooping but cost more, need specific litter in some cases and can scare nervous cats. Check the minimum cat weight for the sensor.
  5. A common guideline is one box per cat plus one, placed in quiet spots away from food and water.

How many litter boxes do I need for multiple cats?

The standard rule is one box per cat, plus one extra. Two cats need three boxes, three cats need four. This applies even with a self-cleaning box, because cats can be territorial about a shared box regardless of how often it cycles. If space is the constraint, a single high-capacity automatic box like the CATLINK Luxury Self-Cleaning Litter Box reduces how strictly you need to follow the rule, but it does not eliminate the need for at least two access points in a two-cat home.

Do automatic litter boxes work for multiple cats?

Yes, and they are usually a better fit for multi-cat homes than manual boxes, since the automatic cycle after each use means the next cat rarely encounters a dirty box. The limiting factor is waste bin capacity. A small waste drawer fills up fast with two or more cats using it daily, so check the rated capacity (in cycles or days) against your household size before buying.
