Why Catlog Exists

We built Catlog after watching too many cats suffer from silent diseases that could have been caught earlier. Cats hide their pain until it's often too late - and too expensive to treat.

We love that cats are independent. But somewhere along the way, we confused "independent" with "fine when left alone." The truth is, your cat spends most of their day without you watching - hiding discomfort, changing their habits in ways you'd never notice. By the time symptoms become obvious, the disease has often been progressing for months.

Catlog monitors your cat 24/7, tracking the patterns you can't see when you're at work, asleep, or just living your life. It catches the subtle changes - shifts in drinking, activity, sleep - that signal something's wrong before it becomes a crisis.

You can't be home all the time. But Catlog can.

Our mission is simple: Use technology to give you more time with your cat.

Every cat parent wants the same thing - more days, more years, more moments together. We can't stop aging or prevent every illness, but we can catch problems early. Early detection means better outcomes, lower vet bills, and often, significantly more time.


The Track Record

Since launching in Japan in 2020, Catlog has monitored over 45,000 cats for more than 12 million hours. Our algorithm has been refined by real veterinary cases, not just lab testing. We've helped detect early warning of many health conditions before symptoms became obvious.

Japan leads the world in miniaturized health sensors and non-invasive monitoring technology. The same precision engineering that goes into medical devices is built into every Catlog collar. But we know you need local support - that's why we have US-based customer service and fast domestic shipping.
