Atom's last year — what the data told us, and what I missed

“I read the data for six months. The signal was there. I was watching the wrong metric. The metric a healthy dog tracks is not the same metric a sick dog tracks. Different dashboards for different stages.”

Behavioral AI on pet cameras — what works, what's marketing

“The behavioral AI that works in 2023 lives in veterinary clinics with $40,000 high-frame-rate cameras and trained-classifier pipelines for lameness detection. The behavioral AI on a $250 consumer camera doing 'is your dog happy' is marketing. The category distinction matters.”

Petivity smart-litter — multi-cat analytics, built by Purina

“Petivity tells Joule from Boson with no microchip and no collar — just a scale and a model. That's the genuinely hard problem this category has dodged for years. The catch is who built it, and what the app wants to sell me on the way out.”

Halo Collar — I tried it, returned it within the trial window

“Halo's GPS-fence engineering is impressive — sub-meter accuracy, low-latency boundary detection, multi-mode correction options. The application — delivering uncomfortable stimuli to a dog who doesn't understand the boundary as an abstraction — is where the engineering excellence stops mattering.”

Quark arrives — a second dog, and the pet-IoT baseline starts over

“Same engineer, second puppy, nine years apart — and the collar I reach for without thinking is the one that didn't exist last time and isn't owned by a pet-food company. That's the whole arc of this notebook in one purchase.”

Whistle Health & GPS+ — the 'health' collar with no vital sign

“A collar that infers how your dog feels from how your dog moves is a clever accelerometer, not a medical device. Whistle calls scratching and licking 'health monitoring.' It's behavior monitoring with a wellness score on top — and the heart rate everyone actually wants still isn't on any consumer collar you can buy.”

AirTag on Atom's collar — anti-stalking vs pet tracking

“AirTag's anti-stalking features are designed to alert an unsuspecting person that an AirTag is following them. When the AirTag is on your dog who's exited the geofence, your dog gets the 'someone is tracking you' chirp. Apple's design assumes the tagged entity is a person, and pet tracking breaks that assumption in interesting ways.”

Litter-Robot multi-cat detection — Joule vs Boson

“Multi-cat attribution by weight works when the cats are weight-different. Litter-Robot's data plus a 30-line Python script give per-cat analytics today, despite the official app not supporting it.”

Boson arrives — the multi-cat engineering problem

“Multi-cat households break the single-cat assumption in every pet-IoT device. The 'which cat is using this?' question becomes the central engineering problem. Some devices have already solved it. Most haven't.”

Petnet collapses — the pet-IoT cautionary tale, written

“A week-long outage isn't a bug — it's what a company looks like when there's nobody left to fix it. The thing that promised to feed your cat couldn't, for a week, and couldn't tell you why. The 'smart' became the failure mode.”

Litter-Robot III Connect — the first pet IoT device with real medical telemetry

“This is the rare connected pet device where the data layer adds something the dumb device can't: visit frequency, duration, and weight are the exact signals a vet reads for UTIs, diabetes, and silent weight loss. The litter box sees them every single day. The yearly checkup sees them once.”

SureFlap Hub — finally, a connected cat door for Joule

“The real win isn't knowing Joule went outside — I knew that. It's that three-to-four trips a day is now a baseline, and the day it drops to one is a health flag I'd never have caught by eye. That's what telemetry does that direct observation can't.”

SureFlap microchip cat door — Joule's first pet IoT

“I keep calling it Joule's first IoT device. It isn't, really. There's no network in it anywhere — no Wi-Fi, no app, no cloud, no second device to talk to. It's a battery, a coil, and a latch that knows one number. That's the honest description, and it's the most interesting thing about it.”
