A smart cat toilet monitor helps with multi-cat health monitoring by logging each cat’s litter box visits separately, so you can see which cat is going more often, staying longer or producing different stool. Siipet’s version is LitterLens, a camera that attaches to your existing litter box. It records visit count and duration, stool shape and colour, and urine clump events for each cat. It does not diagnose or measure weight, and your vet interprets what the log shows.
What Is a Smart Cat Toilet Monitor?
The name suggests a device that replaces the litter box. LitterLens does not. It is a camera unit that you attach to the litter box you already use, and the app turns each visit into a log entry. The box itself can stay the same, and so can the litter.
Because the log is kept per cat, the device suits two situations where manual checking struggles: homes where several cats share a box, and homes with an older cat whose habits change slowly. Related reading: monitoring multiple cats’ health and the senior cat health monitor guide.
What Pain Points Do Cat Owners Face Today?
In a multi-cat home, similar-looking cats make it hard to know who left what in the box. A problem in one cat can hide behind the routine of the others until it is obvious.
Slow changes are also hard to catch by eye. A cat that goes a little more often each week looks normal on any single day, and the change only shows up when someone compares weeks.
Long work days and travel add to it: you cannot check the box, and there is no record of what you missed.
Why Do Traditional Solutions Fall Short?
Manual observation takes daily effort, and the notes vary from one day to the next. It is easy to miss a change in frequency, and in a shared box there is no way to tell which cat it was.
Self-cleaning litter boxes take care of hygiene, and they remove the waste before you can look at it. LitterLens is not recommended for automatic or self-cleaning boxes, and Siipet does not sell them.
Vet visits remain essential, but they happen every few months at best, and the vet only sees one day. A daily log fills the space between visits.
What Does LitterLens Track for Each Cat?
LitterLens attaches to standard litter boxes larger than an L size (over 50 x 38 cm). You label each cat once in the app, and the AI groups later visits by cat. Recognition is around 80% or better, drops above 5 cats, and the app supports up to 10.
For each cat it logs visit frequency and duration, stool shape (hard, soft or watery) and colour, and urine clump events. After about 7 days it has a baseline for each cat, which becomes stable at around 30 days, and it flags deviations from that cat’s own pattern. Abnormal stool and data alerts need a Care+ subscription.
The hardware records at 1080p and 15 fps, is IPX5 water resistant, and runs about a month on its 5000 mAh battery at typical use. A privacy mode turns the camera off when you want it off.
How Does a Camera Compare With Manual Checks?
| Feature | Manual checks | LitterLens |
|---|---|---|
| Which cat | Guesswork in a shared box | Individual recognition, around 80% or better |
| Visit count and duration | Not recorded | Logged for each cat |
| Stool changes | Seen only when you scoop | Shape and colour from stool images |
| Trends | Depend on your notes | Baseline per cat from about 7 days |
| Alerts | None | Abnormal stool and data alerts with Care+ |
| Box compatibility | Any | Standard boxes larger than an L size; not for automatic boxes |
The camera does not tell you what is wrong. It tells you that something changed and when, and that gives your vet a starting point.
How Do You Set Up and Use LitterLens?
Mount the camera: attach it to a flat surface on the box. Adhesive mounting is the default, and a clip is available for open, low boxes.
Connect via app: pair with your home Wi-Fi. The app builds a baseline for each cat over about 7 days.
Label your cats: mark each cat once so later visits are sorted by cat.
Choose a plan: the free tier covers live view, recording, visit data and low-battery alerts. Add Care+ for abnormal stool and data alerts.
Review the timeline: a quick look daily and a fuller review each week. Recharge about once a month.

How Does It Help in Multi-Cat and Senior Cat Homes?
Multi-cat homes. With two cats sharing a box, the log tells you which one is visiting more often or leaving loose stool, so you know which cat to book with the vet. LitterLens covers the box it is attached to, so each box needs its own camera. The two-camera bundle suits homes with two boxes. Adding a second box is a separate question that our guide on two litter boxes for two cats answers.
Senior cats. Older cats are more prone to conditions such as kidney disease, which often shows up as increased urination. LitterLens does not detect kidney disease, but it can show that a cat’s urine clump events or visits are climbing over weeks, which is a good reason to ask for a vet exam. The Cornell guide to chronic kidney disease explains the signs. Browse the senior cat monitoring collection for options.
What Can a Cat Toilet Monitor Not Do?
It does not diagnose. It does not measure weight, and it does not detect kidney disease, urinary tract infections, bladder stones, vomiting, parasites or dehydration. It cannot see posture or straining. What it does show is changes in visits, stool and urine clump events, which your vet can then check with an exam and tests.
A male cat that goes to the box repeatedly and produces nothing is an emergency, and so is a cat with no urine for 24 hours. Call your vet without waiting for an alert.
