FAQ Section
Can an automatic litter box really handle two cats?
Yes—especially top models like the Litter-Robot 4. Just remember to empty the waste drawer a little more often with two cats.
Do I still need two boxes?
Many experts suggest one box per cat plus one extra. For most two-cat homes, a high-capacity automatic box is enough, but some cats prefer their own space.
Will my cats be afraid of the noise?
Most premium automatic litter boxes are designed to be quiet. Nervous cats usually adjust after a few days. Introduce the new box slowly to help them get used to it.
What litter works with these boxes?
Litter-Robot 4 and PetKit PuraMax 2 use standard clumping litter. PetSafe ScoopFree requires special crystal litter trays. Always check your chosen model’s requirements.
How often should I empty the waste drawer?
For two cats, plan on every 2–3 days. Smart models will send an app alert when it’s time to empty.
