The Litter-Robot 4 Supply & Accessory Bundle by Whisker pairs the flagship globe-style automatic self-cleaning litter box with a comprehensive accessory kit. The unit features a rotating globe mechanism that cycles after each use, sifting clumping litter and depositing waste into a drawer below. It accommodates clumping litter, holds waste for up to 2 weeks for a single cat, and is suitable for multi-cat homes (2–3 cats). The app tracks litter box usage, provides health insights, and includes WiFi connectivity for remote monitoring. The bundle adds practical value with a mat, odor-control carbon filters, pre-measured liners, and cleaning wipes. Known for reliability and industry trust, it commands a premium price; best suited for tech-savvy owners willing to invest in hands-off litter management and remote monitoring. Note: This is a bundle listing (accessory tier), not the standalone unit.
