Why it matters
Whisker's own liners are custom-fit for Litter-Robot waste drawers, holding 9 to 11 gallons. On the Litter-Robot 4 you wrap the edges over the drawer rim; the Litter-Robot 3 has its own fitting method.
The Whisker app notifies you when the drawer is full; lift out the liner, discard it and fit a new one. The pack has 25.
