Buying Guide: Key Purchase Considerations

  • Clump Strength and Consistency: Look for hard, fast-clumping formulas that hold up during The Perfect Cycle to prevent moisture from reaching the base of the tray.
  • Dust Levels: Low-dust or dust-free options reduce tracking and respiratory irritation for cats and humans, which is especially important with enclosed or semi-enclosed robot systems.
  • Odor Control: Choose litters with long-lasting odor control, especially for multi-cat homes or basements and apartments where odors can accumulate quickly between automatic cleanings.
  • Dust and Allergies: Hypoallergenic or unscented formulas help sensitive cats and owners, reducing irritants that can affect litter box usage.
  • Maintenance and Scooping: Litters with easy scooping or non-stick properties can streamline maintenance with a robot, minimizing jams and downtime between cycles.
  • Box Compatibility: Some formulas are marketed as best for Litter-Robot units; however, performance often translates well across other self-cleaning systems and standard boxes alike. Consider your model and cycle settings when selecting.
  • Bike-Side Considerations: For households with multiple cats, multi-cat formulas with stronger odor control and larger clump formation can reduce the frequency of box changes and improve overall cleanliness.
