You know that sinking feeling when you scoop the litter box and wonder if something looks off about your cat’s waste.

This guide covers five top models from PETLIBRO and Garvee that offer this advanced health monitoring. Whether you have a single cat or a multi-cat household, these boxes help you stay proactive about your feline’s wellbeing.

Buying Guide

AI Waste Analysis Accuracy

The core feature of these litter boxes is the built-in AI camera that examines waste. PETLIBRO’s models, like the PETLIBRO Automatic Litter Box with Accessories Kit, use computer vision to differentiate between urine and stool, and even detect loose versus solid stool. This data is logged in the app so you can spot trends over time. Garvee’s box relies on weight and app-based tracking but lacks a dedicated camera for stool analysis. For a deeper look at tracking specific waste types, see our best smart litter boxes with stool tracking page.

Multi-Cat Recognition

If you share your home with several cats, knowing which cat’s waste is concerning is crucial. PETLIBRO’s AI recognizes up to ten cats from multiple angles, logging individual usage and weight trends. Garvee’s model also offers weight-based identification but may be less precise in crowded households.

Odor Control System

No one wants a smelly litter box area. All PETLIBRO models include a built-in fan and activated carbon filter that eliminates up to 97% of odors (third-party validated). The sealed base and waterproof mats prevent leaks. Garvee uses a deodorizing design with an aromatherapy diffuser, but its odor removal isn’t as rigorously validated.

Ease of Maintenance and Safety

Self-cleaning should mean less work, not more. PETLIBRO boxes have a 2.9-gallon sealed waste drawer that holds up to 14 days of waste for one cat. Garvee offers a 13L bin for up to 15 days. Safety features like visual, weight, and infrared sensors ensure cleaning pauses when a cat approaches. PETLIBRO’s multi-check anti-pinch system is especially thorough.

Can smart litter boxes distinguish between urine and stool?

Yes, models like the PETLIBRO line use computer vision to separate number one from number two. They also detect solid versus loose stool, giving you a detailed health picture. Garvee’s model relies on weight and usage patterns rather than direct visual analysis.

Are these litter boxes safe for multiple cats?
