Litter-Robot 4
VERDICT
It costs as much as a flagship smartphone ($700), which sounds insane for a litter box. But ask anyone who owns one, and they will tell you they would pay double. The LR4 fixes the noise and design issues of the previous model, offering a whisper-quiet operation and sophisticated health tracking for your feline friend.
The Big Picture
The concept is simple but brilliant: a rotating globe that sifts litter automatically. The Litter-Robot 4 refines this with advanced laser sensors (OmniSense) that are safe for cats of all sizes (even kittens over 3lbs). It connects to Wi-Fi to tell you exactly when the waste drawer is full, so you only have to deal with it once a week instead of every day.
⚖️ SmartScale Health Tracking
The Innovation: It weighs your cat every time they enter.
Why it matters: Sudden weight loss or increased bathroom visits are often the first signs of illness in cats (like kidney disease or diabetes). The app graphs this data over time, acting as an early warning system that could save your pet's life.
👃 OdorTrap System
Breathe easy.
Design: The waste drawer is tightly sealed, and you can add optional OdorTrap pods (or carbon filters) to neutralize smells. Unlike open litter trays, the waste doesn't sit exposed to the air, making your home smell like a home, not a zoo.
✅ The Pros
- Never Scoop Again: Just change the bag once a week.
- Quiet: The motor is practically silent compared to the loud LR3.
- Cat Friendly: The wide opening makes it inviting even for large cats.
- App: Excellent notification system for drawer fullness and errors.
❌ The Cons
- Price: Very expensive initial investment.
- Size: It is huge and dominates any room it is in.
- Sensor Cleaning: Laser sensors can get dusty and need wiping occasionally to prevent errors.
🤔 Should you buy it?
YES if you have multiple cats or travel frequently (keeps the box clean while you are away).
NO if your cat is extremely timid and scared of moving objects (get a simpler automatic rake system like PetSafe ScoopFree).
