✅ What to Look for in a Multi-Cat Self-Cleaning Litter Box

1. Capacity – Look for a large waste drawer and bowl to accommodate more frequent use.
2. Durability – More cats = more wear and tear. Choose a model built to last.
3. Odor Control – Must-have in a multi-cat home. Carbon filters or crystal litter help.
4. Noise Level – Quieter operation reduces stress for skittish cats.
5. Ease of Cleaning – Even self-cleaning boxes need occasional manual cleaning.
6. Litter Compatibility – Some boxes require specific litter types.

🐈 Tips for Success with Multiple Cats

• Have one litter box per cat, plus one extra, even if some are self-cleaning.
• Introduce the box slowly — let cats get used to it before removing their old box.
• Scoop backup boxes manually if needed. Not all cats will use the same box.

Final Thoughts

A self-cleaning litter box can be a game-changer for multi-cat households, saving you time and keeping your home cleaner. While the Litter-Robot 4 is our top pick for its advanced features and reliability, options like the PetSafe ScoopFree Ultra offer great value with minimal effort.

Choose the model that best fits your home, budget, and your cats’ personalities — and enjoy less scooping and more cuddles.
