**Litter-Robot** is a leading brand of automatic, self-cleaning cat litter boxes developed by **Whisker** (formerly AutoPets), an American pet-care technology company headquartered in Auburn Hills, Michigan. Created in 2000 by engineer and inventor Brad Baxter, the brand revolutionized pet care with its patented gravity-driven sifting globe design, which automatically separates waste from clean litter without the use of traditional, mess-prone rakes. Operated globally and integrated with smart technology via the Whisker app—offering real-time usage tracking, waste-drawer alerts, and multi-cat health monitoring—Litter-Robot has grown into a premier, premium staple for modern pet owners looking to eliminate the chore of manual litter scooping.
