Google's Pet Memory AI Can't Tell One Cat From Another
A two-week real-world test found Google's new feature for identifying individual pets on Nest cameras keeps calling every cat by the same name, with consequences that go beyond the comical.
Key points
- Google's Pet Memory feature, part of the Google Home Advanced Plan at $20 a month, promises to teach Nest cameras to recognise individual pets by name.
- After two weeks of testing with three cats, the system identified every animal as Smokey, the first cat entered into the system.
- The feature works only on indoor Nest cameras, not outdoor ones, and offers no way to upload photos or correct misidentifications.
- Misidentification triggered a pet feeder for the wrong cat repeatedly, overflowing the food bowl within a single day.
- Google had not responded to questions about the failures at the time of writing.
Google recently launched Pet Memory, a feature for its Google Home smart home platform that is supposed to teach connected Nest cameras to tell your pets apart by name. The idea sounds genuinely useful: instead of a vague "motion detected" alert, your camera would say "Boone is at the door" or "Smokey hasn't come inside yet." A reviewer at The Verge ran the experiment properly, with three cats, a dog, a kitten, and two weeks of patience.
The short version: it does not work.
What is Pet Memory supposed to do?
Pet Memory lets you type your pet's name, breed, and description into the Google Home app's chat assistant, and Gemini for Home, Google's AI built into the smart home platform, saves that information. From then on, cameras are meant to cross-reference what they see against those saved profiles and give you personalised alerts.
The pitch is a real step beyond what cameras can do today. Most security cameras still only detect motion. Smarter ones, from brands including Ring, Wyze, and Apple's HomeKit system, can now say whether they saw a person or an animal. Google claims to go further and name the animal.
Access costs $20 a month on the top-tier Google Home Advanced Plan, and the feature currently runs only on indoor Nest cameras.
Does it actually recognise individual pets?
No, not reliably. The test involved three cats with clearly different appearances: Boone, a tuxedo cat with white paws; Osa, a tabby kitten; and Smokey, a large grey-and-white cat. Every sighting, regardless of which cat walked past the lens, was labelled Smokey.
There is no setup process where you upload photos of each animal. There is no correction tool. You type a name and a breed, and the system tries to work the rest out alone. When the tester added more detailed descriptions, the app said it could not process the extra information.
Here is why that matters in practice:
| Problem | Real-world result |
|---|---|
| Every cat called Smokey | No way to know which cat was home |
| Wrong cat triggered feeder | Food bowl overflowed in one day |
| "Smokey in garage" alert | Footage showed Boone in the laundry room |
| Daily Home Brief summary | Reported "many pet interactions" with no useful detail |
One alert said Smokey was eating in the garage, which set off alarm bells because cats getting into a garage can mean trouble. Checking the footage showed Boone in the laundry room, exactly where he should be. The garage camera confirmed no cat had been there all day.
What does this mean for pet owners thinking of signing up?
Skip Pet Memory for now if accurate pet identification is the goal. A wrong name on a notification is one thing. Relying on the system to confirm all your animals are safely inside before dark is another, and this feature is not ready for that kind of trust.
The underlying camera descriptions that Gemini for Home produces, the plain-English summaries of what the camera actually saw, are genuinely better than a simple motion alert. Those are worth having. But personalised pet ID, the headline feature, needs significant work before it earns a place in anyone's daily routine.
Google has not yet explained why the system behaves this way or when a fix might arrive.
