This post is in collaboration with Moggie, who provided their product in exchange for my honest review and experience using their product.
An activity tracker is not a medical device or a substitute for veterinary care and is only a tool to aid in their care. Always consult your local veterinarian professional.
Caring for our cats means paying attention to the little things. Subtle changes in appetite, sleep, and other behaviors that can signal when something’s not quite right. The challenge is, those early signs are easy to miss, and we can’t watch our cats around the clock.
That’s where Moggie, a cat activity tracker, comes in. It tracks everything from playtime to rest, giving us insights we might otherwise overlook. But the real question is: can a simple tracker actually make us better cat guardians? That’s what I wanted to test.
Why Monitoring Matters
Back in June of 2025, my husband and I had to say goodbye to our cat Leon shortly after we noticed he didn’t eat lunch or dinner, which was unusual for him. We took him to the vet the next day to find out he had a tumor growing on his liver.
Looking back, even now, I’m not sure how long he had been hiding the signs of his illness. Cats are experts when it comes to hiding their pain or discomfort until it’s much further along.
That’s what I appreciate about Moggie. They want to support your cat’s health by monitoring for more subtle signs we might otherwise miss. If Leon had been wearing a tracker, I might have noticed his decline earlier. It wouldn’t have prevented his illness, but it could have helped me make him more comfortable, sooner.
Moggie isn’t just for senior cats though, I think even kittens and younger cats would benefit. If you establish a baseline for what’s normal for them, when something inevitably does go wrong, you know sooner rather than later.
Unboxing Moggie
Initially, one of my concerns was how Luna would react to wearing the collar and tracker, especially having not worn a collar in several years. However, when I opened the Moggie box, I noticed how small and lightweight the tracker was. And sure enough, once I tried it on her she had no trouble wearing both. Some cats may need more of a transition period or training though.
I also liked that the activity tracker wasn’t over designed. The tracker looked like a natural add-on for my cat’s collar, even less bulky than an AirTag. It attaches to the collar with a simple strip of hook-and-loop. I did decide to take off her hanging ID tag though, as the two would click together as she walked and I thought that might be bothering her.
It also came with a Hub and a split USB-C cable for charging the tracker and powering the Hub. However, you will need your own collar and USB-C wall plug or adapter to plug it in as neither are included in the package.
Setting Up Moggie
Setup felt intuitive. I simply downloaded the app through the QR code on the box, plugged in the tracker and the Hub and input my cat’s data like her age and her health issues. It took less than 10 minutes to be fully set up and start the trial period of collecting data.
Speaking of data collecting, the app shows their activities right away, but accuracy improves over time as it learns your cat’s baseline. It takes a full 7 days to collect enough data to get your cat’s personal averages for each activity.
What Activities Are Tracked?
At the time of writing this post, the app currently supports tracking for walking, jumping, resting, grooming, playing and sleeping.
In the future it will also support the tracking of eating, drinking, litter use, scratching and more. I’m currently testing some of these features in beta so these features will be in some of my screenshots.
Health Tracking
This is the main feature and section of the app that I reference the most.
I never realized how much Luna groomed until I saw the numbers. That plus jumping and sleeping are her highest logged activities. Sleeping makes some sense for her age, but I can always tell when she’s due for her osteoarthritis injection because her jumping and walking decline and her sleep goes up.
Weight Monitoring
One underrated feature I haven’t tried yet is weight monitoring. I need to get a scale, but even if you just log their weight when you visit the vet it can be a great indicator of health and wellness.
For Luna, this would be making sure she doesn’t lose weight. For some cats it might be making sure they are losing weight on a weight loss journey or for tracking growth in kittens. It’s just nice to have all of your cats' health data in one place.
Reminders
Remembering everything that you need to do for your cat's care can sometimes be a challenge. As someone with ADHD, I often struggle to remember little tasks like nail trims, water filter changes, or vaccine schedules. I really appreciate this extra yet important feature called Reminders, which are customizable alerts that help you stay on top of care.
Weekly Reports & Chat Feature
Another neat feature is that you don’t have to analyze the data yourself. The app gives you a weekly report and highlights any trends in their behavior that could be monitored and tweaked.
For example, in this screenshot you can see that there was a significant decrease in Luna’s jumping and playtime this week. The chat feature is a lot like Chat GPT, you can ask it for suggestions such as how to increase her playtime.
It’s not a quick response like other A.I. bots so you’ll have to give it several minutes to answer. I’m hoping with time, this feature will improve in speed. When it did give me an answer it responded based on her recent data and took into account her medical conditions so it wasn’t just a generic response.
Using Pet Data to Become a Better Cat Guardian
So let’s come back to the question I originally asked. Can tracking your cat’s habits actually improve their care?
In some ways, I’d say yes. The data that Moggie tracks can be shared with your vet to give you early clues into what might be going on. Even small changes are good to note because they might indicate stress or pain, not just illness.
Having the app tell me when there’s a dip in a particular area or it notices a trend means I can adjust my care routine to adapt quickly to Luna’s needs week by week.
For example, I noticed one week that Luna was playing less, it was a great reminder to play more often with her to keep her average up and promote her mental and physical wellbeing.
What does Moggie cost?
At the time of writing, for a Moggie activity tracker and Hub the cost is $99.00 USD, including free shipping and taxes (in the US and UK). Each additional activity tracker is $49.00 USD.

Is Moggie worth it?
For the price, I think that it’s a great tool to have in your care kit. Whilst not crucial to their wellbeing, there’s no subscription so I think it’s a great one time investment for added peace of mind and enhancing your cat care routine. Additionally, with long term use and more data, the tracking and accuracy should continue to improve with time overall. The app is really robust with features as well, so overall I personally think it’s worth it.
FAQ
Does Moggie work with iOS and Android?
Yes. Moggie is compatible with both iOS and Android.
Does it need Wi-Fi?
Yes, you need a reliable Wi-Fi connection for Moggie to track your cat's activities.
How long does the battery last? How long does it take to charge?
The battery needs about 2 hours to charge and should last roughly 4 weeks depending on your cat’s activities. The app notifies you when it’s done charging.
How accurate or reliable is the tracking?
It’s hard to tell the accuracy, but I can definitely tell the ones in beta are less reliable than the ones currently available to non-testers.
If I have more than one cat, do they need multiple trackers?
You need multiple trackers but only one Hub to track multiple cats. Each cat will have their own profile in the app. To purchase the tracker only you can get it here.
Can cats wear this 24/7?
Yes, it’s meant to be worn consistently to track data accurately. The exceptions would be near water as it’s not waterproof or when charging.
Can I use Moggie if my cat goes outdoors?
My cats are indoor only, and since it needs to be in proximity to the Hub I would assume that the Moggie will not work if your cat is outdoors.
Can vets access the data directly?
Not exactly, not live data anyway, however you can send them a photo of your cat's stats directly from your phone with the share button or a screenshot.
What if my cat won’t tolerate a collar?
I would suggest first getting them used to a collar with clicker training. My favorite guide for collar training is this video by Cat School.

The Future of Feline Care
As an anxious cat guardian myself, I notice a lot about my cat, but I’m not perfect. That’s why I’m curious about how A.I. can support us in caring for our cats in the years ahead. As of now, I see Moggie as one more tool in my care toolkit and helping me feel more confident and attentive as a guardian.
