I tested the Litter-Robot 4 in a two-cat apartment for 60 days. The difference between this and older robotic boxes is night and day: the Litter-Robot 4 is whisper-quiet. You can stand four feet away while it sifts and barely hear a faint hum.
The wider oval entrance and lower step height made my timid 9lb rescue cat hop in on day two without hesitation. The Whisker app is a revelation: it tracks each cat’s exact weight after every visit. When my male cat visited four times in one morning without urinating, the app alerted me, and we caught an early urinary tract infection before it became an emergency. You empty the waste drawer once every 10-12 days for two cats. It completely transforms cat ownership.
