HOW IT WORKS

From Stranger to Health Guardian
in 2 Weeks

WEEK 1-2: Learning Mode

Catlog studies your cat’s unique rhythms. Every cat is different—some are dawn sprinters, others are midnight snackers. The AI builds a personalized “health fingerprint” so it knows what’s normal for your cat.

WEEK 3+: Guardian Mode Activated

Now Catlog can detect meaningful changes. Not just “your cat moved less today” but “your cat’s resting heart rate is elevated + drinking more water + sleeping poorly = potential renal system stress—consider a vet check.”

THE RESULT?

You catch problems early, when treatment is easier and cheaper. You avoid emergency vet visits. You stop second-guessing every yawn, that extra nap.

Lightweight. Comfortable. Beautifully crafted.

With "invisible" tech that actually matters.

Will update

This thing is cool! I've been looking for something like this for 2 years. Since July 2022 when ine of my other cats passed away. It's December 2024 right now. Moderately easy to set up. Yes there is a subscription, 15, 10 or 8 dollars a month if you pay for 1 or 2 years for the cheaper price. Yes it does say that in the description. I read ever single review, I saw every picture and video. I've only had it for 2 hours and I love it. I have 2 cats. One 15-year-old female. One 5-year-old male. I ordered a large for my 15 year-old based on her weight and the chart. It's too big for her, so I adjusted the settings and data and put it on the 5 year-old male because he is bigger and more active. I immediately ordered a Medium for her. I originally wanted one for my 15yearold female because she's older and I wanted to generally keep better track of what she's doing. But for now the boy will wear it and I can see how accurate it is. It's pretty darn good on him. When she wore it for an hour it was a little off in what she was doing but I think that was because of the size. On him, it's pretty accurate. Not 100% but a decent 95%. Given it's only been 2 hours between the both. I'll update in a few weeks or in a minth but for now I'm excited! I hope it lasts and that there will still be more available when the time comes to replace. I can't put a price on my cats health. I'd pay anything to have the one I lost few years ago back.

Great for cats that are outdoor animals!

Returned product. Did not need. Our cat is strickly an indoor kitty! Great idea for kitties that go outside, though!

Amazing tool for health monitoring — works perfectly with the Catlog Board!

I’m absolutely thrilled with the Catlog system. I’ve been using both the Catlog smart collar and the Catlog Board (the smart litter mat), and together they give me a complete, real-time overview of my cat’s daily health.💡 It tracks literally everything: • Meals (even short snacking attempts!) • Drinking times • Sleep patterns and rest quality • Breathing rate and surface temperature during sleep • Weight trends and toilet behavior (with the Board)I use it for a cat with chronic health conditions, and this system gives me a level of insight that no other pet tech ever has. It helps me catch subtle changes before they become serious.The only downside? I live in Europe, and the app currently shows everything in US/Japan time. So I manually convert the times (+6h) when reviewing data. It would be amazing to have European time zone support in the future.Still, this is one of the best investments I’ve made as a cat guardian. If you love data and want to track your cat’s wellbeing precisely — Catlog is brilliant.Highly recommended!

For the love of cat, get this.

First, some advice: If your cat has never worn a collar before, make sure to measure their neck circumference under their fur, not over. Maybe that's obvious, but it didn't occur to me so the collar I ordered was too big. Under his fur, where the collar actually sits (duh, me), his neck circumference was an inch smaller.The collar: It's lightweight and sturdy. It took about a day for my cat to adjust to wearing it after never having worn a collar at all and, despite spending most of the first day scratching at it, it still looks perfect aside from a loose thread. That said, for economic and ecological reasons, I hope the pendant can be transferred to a new collar should the need arise.The app: It's cute, clean and informative. I love the various ways data is presented and the fact that you can enter your cat's dietary info to find out how it compares to your cat's energy needs. I've noticed some incidences where the activity reporting hasn't been accurate, but it's good overall. Even tech for humans isn't perfect.Final thoughts: I, unfortunately, have learned from experience that changes can happen slowly and go unnoticed, especially with how busy our lives can be. And, sometimes, by the time you notice, it's too late. I've been beyond eager for this product to become available in the US because I love anything that can help me be a better pet parent and maybe give me more time with the furry little ones I love so much.

Peace of mind

I bought this because my cat has a heart condition and I want to be able to keep an eye on his heart rate. It is not 100% accurate, but it is close enough and gives me of mind!
