    Whisker announced on October 21, 2025 that the Litter-Robot 5 Pro at $899, Litter-Robot 5 at $799 and Litter-Robot EVO at $599 were available for sale in the U.S. that day. Press coverage reported the three models the same day, and a news report on October 22 said all three were available to order with shipping expected by November 30.

    EVO Positioning

    Press coverage describes the EVO as Whisker’s cheapest robot, smaller than its other models and able to accommodate up to two cats. It reports that the EVO lacks the Litter-Robot 4’s automatic night lights and litter-level sensing but adds a new LCD display, and that the Litter-Robot 4 would continue at $699.

    App Features

    Per press coverage, all the robots connect to the Whisker app for remote cycling, usage alerts, and activity and weight tracking for each cat. More detailed insights require the Whisker+ subscription, which the report lists at $7.99 a month.
