🫳 What Are Smart Litter Boxes?
Smart litter boxes are automated systems designed to:
- ✔ Self-clean after your cat uses the box
- ✔ Control odor with filters or enclosed chambers
- ✔ Track litter usage, urination patterns, and weight
- ✔ Send health alerts via Wi-Fi or Bluetooth apps
These products reduce the hassle of scooping and also provide early indicators of feline health problems like UTI, obesity, and dehydration.

🧠 How Smart Litter Boxes Work (Scientific Mechanism)
- Infrared or weight sensors detect when your cat exits the box.
- Rotating barrels, rake systems, or conveyor belts clean waste into a hidden compartment.
- Odor filtration uses carbon, ozone, or HEPA technology.
- Mobile apps track visits, usage patterns, and health alerts (e.g., sudden increase in urination).
