Pet smart hardware shifts toward emotional companionship, using AI to generate a cat's MBTI diary to satisfy owners' emotional needs rather than surveillance demands.
A while back, I sat down for an interview in Beijing and stumbled upon a pretty intriguing business model. You put a plastic gadget weighing under 18 grams around your orange tabby's neck, and a few days later, a first-person diary entry pops up on your phone, describing that chubby, eat-and-sleep-all-day furball as a "aloof INTJ."
Animal behaviorists would probably shake their heads at that. But among the young pet owners, this thing is turning into a whole new kind of conversation. After chatting with PurrPurr founder Zhao Min that day, she gave me the real scoop. The selling point of this product and tech isn't about what's actually going on in a cat's head—it's about what it appears to be when interacting with people.
I dug into the numbers: by 2025, China's pet spending had already blown past 310 billion yuan, and 62% of that money went toward "emotional companionship." There are now over 70 million cats in the country, but the longitudinal data on what they do 24/7 at home is basically a blind spot. Old-school hardware companies are still obsessed with nailing GPS accuracy or heart-rate stability, while a new wave of entrepreneurs is already using large language models to put a price tag on loneliness. Calculating a cat's MBTI, when you get down to it, is just translating those unspoken moments of companionship into something humans can see and understand.
I don't watch my cat poop—I watch my cat eat
After combing through the pet smart hardware market, I ran into a headache-inducing reality: most products are basically designed to ruin your day.
Picture this: you strap a hefty health monitor on your cat, and it's firing off line charts warning you about an irregular heartbeat. Or you install a camera in the living room, and while your boss is tearing you a new one, your phone pings with a crystal-clear livestream of your cat using the litter box. This whole "total surveillance" gimmick is basically one-way control freakery. Within days, all you've got left is burnout.
Zhao Min shared a story from her own family during the interview. Her mom tracks her and her brother's step counts on WeChat Sports every day. When her brother's sleep schedule goes haywire and his steps drop, Mom swoops in to interfere. He gets annoyed, turns off WeChat Sports, and Mom demands he turn it back on—and in the end, everyone's miserable. That's the classic flaw in traditional monitoring hardware. The devices are cranking out anxiety, telling you how many times your cat hit the litter box or how much it ate, without ever actually delivering any emotional value from your pet.
PurrPurr, by contrast, is taking a much wilder route. I got my hands on the hardware: 17.9 grams, roughly the weight of three one-yuan coins. They brought in an award-winning design team to shape it into cat-ear form. Inside, there's just a digital silicon microphone and a six-axis sensor. No camera, no blood-pressure or temperature monitoring.
I asked Zhao Min why she skipped the camera when even basic feeders come with one these days. She was pretty blunt. She told me she has three cats of her own and spent over 4,000 yuan on Catlink's priciest litter box, but she'd never want to watch them do their business—she'd rather watch them eat, and that makes her happy.
So see, what people want from pets isn't the "truth"—it's "the version I want to see."
Who posts to Moments without throwing on a filter these days? It's the same with pets—raw, unedited documentation is just boring. The microphone picks up a little meowing, the sensor logs a stretch, and all that data goes to the cloud, but what comes out isn't a health report—it's a diary written by the cat itself. Add a label like "social butterfly ESFP," and suddenly this thing becomes the cat's voice in the human world. One friend in the industry told me her favorite part of the day is reading the AI-generated diary for her dog, like "Woke up this morning, stretched, and went back to lying down." Put simply, you're not paying for GPS tracking—you're paying for the joy of having something to post on Moments every day.
Algorithm and empathy: the secret behind "a thousand cats, a thousand faces"
Everyone knows, deep down, that using a sensor on the neck to guess whether a cat is depressed or happy doesn't hold up medically. But this business was never about medical diagnosis. What it's selling is a story the owner actually wants to believe.
When I poked around the system backend, I noticed this "behavior-to-emotion mapping model" is pretty clever. The actions and sounds collected by the hardware are just the foundation. What really brings this cyber-cat to life is a stack of extra variables layered on top, plus the owner's own subjective feedback.
Zhao Min told me the content generation runs through five stages. First, there's the captured real-time behavior. Second, static data like breed, sex, age, and whether the cat is neutered. Third, environmental factors like weather and seasonal markers. Fourth, subjective, imaginative associations. Fifth, the actual presentation format.
They've tapped into large language models, as their technical documentation shows, using prompt engineering to generate images and text. When you set up the profile, you go through an eight-step selection, and the system blends all those parameters together. Even if you have three Siamese cats from the same litter, if you pick different personality preferences at the start, the tone and illustration style of their diaries end up completely different. Zhao Min gave an example: the cat at her Hangzhou home writes diary entries threatening to knock the tissue box off the table if she doesn't come back soon, while the cat in Beijing writes about sneaking into her room again today.
What if you have four cats at home? No worries about data mixing either, because each sensor is locked to a unique physical address—whatever cat wears it, that's whose data gets collected.
The even more interesting part is the feedback loop. The tags the system assigns aren't a one-and-done deal. A diary entry comes through, and if you think today's "aloof" description is spot on, you tap a like. If you think it missed the mark on the cat's sarcasm, you can interact to correct it. Every tap nudges the algorithm.
Over time, this AI isn't getting better at understanding cat biology—it's figuring out what you want your cat to be like. It filters out the negative health warnings you'd rather not see and keeps only the words that sound good to you. Soak in that data long enough, and the AI cat becomes closer and closer to the one in your head. Once those habits are stored up, it's hard to switch to another brand. It's like getting used to Apple's ecosystem—your data's all there, and you can't be bothered to migrate.
Stuck in a factory until her asthma flared up, just so you'd pay 399 a year
At this point, anyone in the know would be a little nervous. In China's smart hardware scene, the hyper-efficient supply chain can humble you fast. Rely on just a bit of cleverness, and you'll get copied down to your last thread. PurrPurr's full-time team of five or six people went from concept to prototype in four months. I asked how they dodged the copycat trap, and the answer was all in supply chain management and financials.
Take the outer shell, for instance. Zhao Min told me that to nail that warm orange matte finish, she spent days and nights at the factory tweaking the ink ratio. Common phone inks add three parts pearlescent, but to get a softer feel, they had to start at two and a half and work up. The workshop was full of workers smoking in an enclosed space, and she pushed through until her asthma flared up. Even the anti-choking buckle went through multiple redesigns, stress-testing it against a 2-kilogram pull threshold. That kind of grind on the factory floor is really about protecting the baseline hardware experience. Because if a cat finds it uncomfortable to wear, the whole software story never gets a chance to start.
Once the hardware was solid, the financial game got sharper.
The little gadget normally sells for 599 yuan, with a limited first run at 499. Even with customer acquisition costs on Tmall, Xiaohongshu, and Douyin running over 100 yuan per new user, the hardware alone still keeps gross margins above 75%. That's better than some big-name hardware players, who start facing losses when margins dip below 65%.
But the real money play hides in the subscription fees. Foreign competitors like SatellAI and PettiChat sell hardware for 399 bucks or more and still charge a subscription. That approach won't fly domestically, so they set up four tiers to test willingness to pay. There's a free tier at 0 yuan for just the basics. Up from that, a 72-yuan-a-year "light" plan with weekly records and one image per week. Then a 129-yuan-a-year "daily" tier. And the top-tier "premium" at 399 a year, with lifetime records, multiple images per day, and a digital birthday keepsake at year-end.
A lot of people think Chinese consumers are stingy when it comes to software, but when I looked at the pet sector data, that assumption fell apart. Devices with cameras, like XiaoPei's, drive subscription attach rates above 90%.
Token costs for large model calls are dropping fast, and they're also splitting image generation into fine-detailed and lightweight modes to cut costs. Run the numbers, and the gross profit on a single user in year one comes to over 400 yuan, with the customer lifetime value-to-acquisition cost ratio above 7.7. The hardware first filters out people willing to spend, then the one-of-a-kind memories convince them to keep paying. They're targeting delivery of the first 10,000 units within the first month, and aiming for 50 million yuan in revenue in the debut year. Once that payment loop clicks, the faster they sell, the deeper the moat gets.
After the cat's gone, who's willing to tap "clear data"?
As the interview wound down, I flipped through Zhao Min's résumé. She's been founding companies since 2010, spent over two decades in education, managed a private-domain pool of over 58 million parents, and run billions in ad spend. Then she pivoted to low-altitude economy and signed deals with over a hundred 5A and 4A scenic spots.
Jumping from selling courses to parents to selling collars to young people looks like a total leap. But strip it down, and the business logic is the same: it's about using a product to fill a hole in people's hearts. Education filled the guilt parents felt about shortchanging their kids; this pet collar fills the need young people in big cities have for a stable source of companionship. Zhao Min joked herself that her past business was driven by greed, anger, and ignorance, while this pet venture is about truth, goodness, and beauty.
When she was 13, her dog passed away, and she grieved so hard she cried for two straight months through the Spring Festival. She didn't dare get another pet for twenty years. It wasn't until 2018 that she started adopting cats—now she keeps three in Beijing and one in Hangzhou. She's always missing the ones in Hangzhou when she's in Beijing, and vice versa. She built this collar out of a simple desire to know what her cats were doing when she wasn't home.
If you just see it as a collar with a diary function, you're selling it short.
Remember those companion robots everyone was hyped about? Plenty of people bought them and let them gather dust within days. It's hard to develop real feelings for a screen you talk at. But living, breathing cats and dogs are a different story. Use a real cat as the anchor, spend seven or ten years recording its sleeping habits, its stretch routines, its meows. All those scattered bits of data pile up and form a digital doppelgänger in the cloud.
It's a model that kind of leaves you speechless. Cats and dogs don't live forever—they'll go eventually. And when the physical body is gone, what's left on the server is years of its movements, thousands of diary entries it "wrote" itself. That digital keepsake happens to catch people right where they fear loss the most. At that moment, who could bring themselves to hit "cancel subscription and delete data"? Even if you don't want to look at it, you want it to stay there forever.
Right now, it looks like a consumer product sold to individuals. But look further, and that cache of first-hand pet home data could feed B-side applications like insurance actuarial work, pet food validation, and veterinary support. And push even further out—if AI biomimetic pets and robots ever become real, this is a ready-made cross-species behavior template library.
Final thoughts
Calculating MBTI for cats or writing diaries for dogs was never about animal science. Like the young people flocking to personality tests, this is about people who are exhausted from the daily grind looking for a place to vent and hoping to hear something back.
The genius of this business is that it doesn't care whether an orange tabby knows what INTJ means. All it cares about is whether, when you drag yourself home at night and a piece of sassy diary text about you pops up on your phone, you're willing to shell out that subscription fee for the echo that actually gets you. We all know that AI-generated log is just a pile of running code, but in this lonely city, it's genuinely something you can buy—a response with a little warmth to it.
