FAQ

Automatic litter box questions for older cats

Is automation better for every older cat?

No; access, sound, movement, litter, and routine all matter.

PuraMax 2 at 7.87 inches.

Can logs diagnose illness?

No; use them with direct checks and veterinary care.

Is Wi-Fi required?

It is used for app records, not all core controls.

Should the old box stay?

Yes, throughout the transition.

When is a change urgent?

Straining with little or no urine can be urgent.
