Litter-Robot (Whisker) tracking FAQ

Where does Litter-Robot ship from?
Whisker manufactures and ships Litter-Robot units directly from its facility in Juneau, Wisconsin.
Why did my Litter-Robot accessories arrive before my Litter-Robot 4?
When you order a Litter-Robot bundle, the robot itself ships in a large 24x24x31-inch carton via FedEx Home Delivery, while liner bags, OdorTrap packs, and litter ship in separate boxes with their own tracking numbers.
Does FedEx require a signature for Litter-Robot deliveries?
Most standard Litter-Robot 4 FedEx Home Delivery shipments do not require a signature unless requested, though you can redirect the box to a FedEx Hold Location if you prefer not to leave the large box on your porch.
