Whether you want to know where your cat goes if they escape outside or monitor your cat’s health and activities, cat trackers can be a great resource for pet parents.
Catlog is an AI-powered cat health monitor that detects when your cat eats, sleeps, grooms, drinks, and more. It also tracks vital signs and can help detect potential health issues early.
Unlike GPS trackers, Catlog focuses on monitoring your cat’s health and behavior rather than tracking their location.
I tested the Catlog Health Tracker on my own cat for about three weeks. In this review, I’ll discuss how the device works, its pros and cons, and if it’s worth the price.
Why Trust Cats.com
Here at Cats.com, our unbiased reviews are based on extensive research, a comprehensive look at customer reviews, and testing the products with our own cats.
This was my first time testing any type of cat tracker, so I was excited to give it a try. I tested it on my 17-year-old cat who, aside from some digestive issues, is pretty healthy for her age.
She’s worn collars before (she hardly even noticed this one was on), but I still paid attention to her comfort level while the tracker was on, as well as how accurate the health monitor was.
Catlog Health Tracker and Brand Overview
Annie Butler / Cats.com
Based in Tokyo, Rabo, Inc. is the company behind Catlog products. Its two main monitoring devices are the Catlog Smart Collar and the Catlog Board, which are available in Japan, the United States, and Australia.
Founded in 2018, the company utilizes animal behavior science and AI to monitor feline health and activity.
While most trackers focus on where your cat goes, Catlog Health Tracker is one of the few collars that tracks activity and behavior. Using advanced AI algorithms, it can detect when your cat eats, sleeps, drinks, grooms, and more.
Catlog Health Tracker Features

The Catlog Smart Collar kit comes with a base station, the collar, and a power cord. The base station acts as a charging dock as well as providing the connection between the collar and your phone. The actual tracker comes as a collar (which is available in several styles and sizes) with a lightweight pendant attached as well as a breakaway buckle.
Its basic function is to detect and record your cat’s activities throughout the day and night, including eating, drinking, walking, running, grooming, resting, and sleeping. It also monitors changes in body temperature and breathing rate, letting you check in on your cat anytime, anywhere.
The Catlog Tracker can detect changes in behavior that may indicate illness, like decreased activity or restless sleep, and may alert you to unusual patterns. It also keeps track of your cat’s litter box usage – if they’re using it too often or not enough. It can even help you compare your cat’s estimated calorie intake with how many calories they burn each day. You can input your cat’s food amounts and type in the app to estimate how many calories your cat consumes, then compare that with the app’s estimate of how many calories they burn based on their activity.
The base station also reports your home’s ambient temperature, which is handy during extreme weather so you can check if your cat might be too hot or too cold.
The app is where you can see your cat’s reported activities, both through live updates and on the “diary” page. You can also get an in-depth look at how your cat’s habits compare day to day, week to week, and month to month.
While the tracker should not be a substitute for veterinary care, it may help identify changes in behavior or vital signs that could indicate a developing health issue.

What Did Our Test Cats Think?

To get started, I downloaded the app, then followed the prompts to connect the base station and add the collar pendant. To connect the base to Wi-Fi, your router needs to support 2.4 GHz. Once the app was set up, I added a profile for my cat, including age, weight, sex, and a photo. As soon as the collar was on, the app began recording the data about her activities throughout the day and night.
It takes about 60 to 90 minutes to charge the Catlog pendant from empty to full. Once it’s fully charged, the battery should last about a week.
I admit, I was skeptical at first, but sure enough, I saw that she was “relaxing” in the app shortly after I put the collar on. She’s usually in the same room with me, but I would take a look at the real time page of the app to see what it was tracking.
The diary page is really helpful, as it summarizes her activities at the end of each day, so I could see how many times she ate and drank, as well as how many hours she spent moving around, relaxing, and sleeping. After a few days of checking the app, most of the information seemed pretty accurate.
We did run into a few glitches, however. For example, I watched her jump onto the coffee table and start drinking from my water glass, but that activity never appeared on the app. There were also some gaps in the data, even though she was near the base station the majority of the time.
For me, the collar was hit or miss. I was impressed with what it tracked on the diary page, like “walked for 34 seconds” or “ate a meal.” And when I was out and about, I could see what she was up to in real time by just checking the app. But I noticed some gaps in the data and instances where it didn’t record something I actually watched her doing.
What Do Customers Think of the Catlog Health Tracker?
At the time of our review, Catlog had 47 customer ratings on Amazon, with an average rating of 3.8 out of 5 stars.
Positive Reviews
Positive reviews praised the device for its activity recording, saying that while there are sometimes gaps in the data, the information is relatively accurate.
“I love this product! I’ve been using it for two months and love the ability to see what mischief my little furball is doing. I love being updated and seeing how many times my cat grooms, drinks, and eats. – Saul M on Amazon
“I was actually able to catch a heart issue super early because of this app. I noticed that my cat literally never moved when I was away at work. He’d just sit or sleep all day. I told his vet, who suspected a cardiac issue and ran some tests. Long story short, my cat now has a cardiologist, and he’s at the beginning stages of a heart issue. There’s no way I would have caught this until he started presenting obvious symptoms.” – Jenny on Amazon
Negative Reviews
One of the top complaints was about the difficulty in setting it up to WiFi. Some reviewers also pointed out that the readings aren’t completely accurate and there are sometimes inconsistencies in the data. Other reviewers were not happy about the price and the monthly fee.
“Collar design and device itself is nice. WiFi setup takes longer than necessary and is unstable and inconsistent.” – Summar on Amazon
“It should state very clearly that you need to pay $15 a month to use the product as it is intended to use. Otherwise, you’re buying a $100 collar to just sit on your cat’s neck and do nothing.” – Ali on Amazon
Overall, Is the Catlog Health Tracker a Good Choice?
While some customers said the info isn’t always completely accurate, they admitted that what they were getting was good enough for their peace of mind. I found that I got a pretty good idea of my cat’s day-to-day habits, even with some data gaps. That being said, this is a new product and some of these inconsistencies might be improved through software updates in the near future.
Another issue is the price. The device itself is $110, but you also have to pay for a subscription to use its monitoring features. There are three options for that: $14.99 a month; a one-year plan at $11 a month ($132 billed annually); and a two-year plan at $8 a month ($192 billed every two years). Whichever you choose, it can get pricey.
But even considering the price and a glitch now and then, it’s a good choice for cat owners who want a little more insight into their cat’s daily routine.
