For parents of two or more cats, some moments are all too familiar: You return home from a short business trip, and the first thing you do is clean up the litter box. But among the usual mess, you spot a soft stool, and you're left wondering whose it is.
According to a 2024 report from the AVMA, the average cat-owning household in the U.S. has 1.8 cats, highlighting that multi-cat households are increasingly common (AVMA, 2024). As a result, the need for long-term health monitoring is growing. Common urinary tract diseases, such as feline lower urinary tract disease (FLUTD) and urinary blockages, are among the leading health threats to cats and can result in life-threatening complications in 30% to 50% of cases if left untreated (JVECC). Yet, the market still lacks effective smart health management solutions designed specifically to meet the unique challenges of multi-cat households.
Toilet Data Mix-ups between Multiple Cats
Traditional litter boxes provide no usage records, leaving important data missing. Most automatic litter boxes rely on weight scales to distinguish cats, but similar weights can still cause data mix-ups. Without a reliable way to accurately distinguish between individual cats, weight fluctuations and overlapping usage patterns can blur the data, making it difficult to track which cat is using the box and whether there are any subtle behavior changes. This confusion can mask early signs of issues like urinary problems or digestive disorders, limiting the ability of pet parents to monitor each cat’s well-being accurately.

Personalized Health Management with AI-powered Automatic Litter Box and Smart App
Missing early signs of abnormal behavior can delay treatment and endanger your pet’s health. That’s why PETKIT developed AI-powered cat facial recognition technology to help multi-cat parents accurately identify each cat and build personalized health profiles through data insights and video records.
The PUROBOT Automatic Litter Box Collection—PUROBOT Max Pro and PUROBOT ULTRA —features the AI-powered camera that uses advanced algorithms to recognize a cat's face and records real-time potty videos.
All your cat’s litter box data and video footage are linked to their individual profile via the PETKIT App, creating a seamless system that turns personalized feline health management from a wish into reality.

Tech Behind Everything
AI-powered Tech for Multi-cat Recognition
- Five-Point Recognition: Our system uses advanced algorithms to extract five unique biometric markers from each cat’s face: the nose tip, both eyes, and both ear tips. These features form a distinct facial profile for each cat, enabling accurate recognition even in multi-cat households.
- AI-Powered Face Matching: Once the facial markers are extracted, the AI compares them to a pre-existing database of registered cat profiles. Using machine learning, the system continually improves its ability to match the cat’s face with its corresponding profile, ensuring that each cat’s litter box data is accurately recorded in real time.
Auxiliary Functions for Multi-cat Recognition
- Weight Measurement: Equipped with four weight sensors, the automatic litter box records your cat’s weight during every visit. It provides an additional layer of identity confirmation while also tracking subtle weight fluctuations, offering health insights for ongoing health monitoring.
