Is there a Fitbit for cats? Yes, activity trackers made for cats exist: small collar-mounted devices that record movement and rest. They do not show bathroom habits, which is where many early health changes appear. LitterLens, a litter box camera from SiiPet, covers that gap by tracking litter box visits, stool and urine clump events, and it does not need to be worn.
Why Is Cat Health Monitoring Harder Than It Looks?
Cats are often indoor pets, and they hide illness well, so subtle health declines go unnoticed. A collar tracker can show how much a cat moved, and it cannot see stool or urination. Low activity can go with weight gain, and your vet confirms that with a weigh-in; the Cornell Feline Health Center covers the topic in its page on feline obesity.
Multi-cat households make it harder, because individual health signals blend together without a way to tell the cats apart. Owners who rely only on visual checks tend to notice a problem after symptoms are visible.
Where Do Cat Wearables Fall Short?
Collar-based trackers, including GPS models, focus on location or movement rather than health data. Battery life and weight vary by model, so check the specifications, and some cats dislike wearing a collar or try to remove it. Step counts are also hard to read for cats that spend the day napping and jumping between shelves.
Feeding bowl monitors and basic activity collars give fragmented data, and they usually cannot tell multiple pets apart. None of these tools see litter box dwell time or stool consistency. PawTrack, SiiPet's other camera, is an indoor behavior camera with auto tracking and 360° pan. It is not a wearable, and it has no GPS.
How Does SiiPet LitterLens Track Cat Health?
SiiPet LitterLens is a litter box camera that mounts inside the box, so your cat wears nothing. It logs each cat's visit count and duration, analyzes stool shape and color, and records urine clump events. It builds a baseline for each cat over about 7 days (steadier at around 30 days) and flags deviations from it.
LitterLens is IPX5 water resistant, and its battery lasts about a month with typical use. It needs a flat mounting surface and a litter box larger than L size (over 50 x 38 cm), and it is not recommended for automatic or self-cleaning boxes. Live view, recording and visit data are free. Alerts for abnormal stool and data require a Care+ subscription. LitterLens does not diagnose anything, and your vet confirms what a change means.
How Does a Wearable Tracker Compare With a Litter Box Camera?
| Feature | Cat Activity Tracker (Collar) | SiiPet LitterLens |
|---|---|---|
| What it measures | Movement and rest | Litter box visits, duration, stool and urine clump events |
| Worn by the cat | Yes, on a collar or harness | No, mounted inside the litter box |
| Stool and bathroom data | Not tracked | Stool shape and color, visit count and duration |
| Multi-cat support | Depends on the model | Recognizes individual cats; accuracy drops above 5 cats, app supports up to 10 |
| Power | Varies by model | Rechargeable battery, about one month with typical use |
| Subscription | Varies by model | Basic monitoring free; alerts and analysis need Care+ |
How Can You Set Up SiiPet LitterLens Step by Step?
-
Charge the camera over USB-C until it is full before first use. A full charge takes about 6 hours.
-
Download the SiiPet app and create an account.
-
Mount the camera on a flat surface at the litter box using the adhesive, or the optional clip for low open boxes, with a clear view and without blocking your cat's access.
-
Connect to 2.4 GHz Wi-Fi in the app and label each cat.
-
Give it about 7 days to build a baseline for each cat, then review the data and share what you see with your vet.
When Does a Litter Box Camera Help More Than an Activity Tracker?
These are situations where litter box data is more useful, and each change still needs a vet to interpret it.
- Senior cats: changes in visit frequency or stool over several weeks are worth showing your vet.
- Multi-cat homes: separate profiles show which cat has soft stool or a change in visits. See how LitterLens tracks multi-cat health.
- Busy owners: a running log and Care+ alerts help when you cannot watch the litter box yourself.
- Diet or litter changes: the data shows whether your cat's stool or visits shift after a change.

When Should You Talk to Your Vet?
Whatever tool you use, some signs need action. A cat that has not peed in 24 hours needs a vet call, and a male cat that strains with nothing coming out is an emergency right now. No stool for 48 hours also calls for a vet, and VCA's page on constipation in cats explains why.
Red or black, tarry stool is worth a prompt call. Our guides to how long a cat can go without peeing or pooping and the stool changes chart explain the details.
The ASPCA also lists medical causes behind cat litter box problems.
FAQs About Cat Trackers and LitterLens
Does LitterLens replace a cat activity tracker?
No. LitterLens does not track movement around the house. It covers litter box visits, stool and urine clump events, so it answers different questions than a collar tracker.
How accurate is SiiPet's multi-cat recognition?
It works well in most homes. Recognition is not perfect, it gets weaker above 5 cats, and the app supports up to 10 cats.
Does SiiPet LitterLens work with automatic litter boxes?
No. It is not recommended for automatic or self-cleaning litter boxes.
What is the battery life of the device?
About one month with typical use of around eight daily visits, with USB-C recharging.
Do I need a subscription?
No for basic monitoring: live view, recording, visit data, 72 hours of local storage and low-battery alerts are free. Abnormal stool and data alerts need Care+.
