Watch the video review: SiiPet Litter Lens video review on YouTube
On Mark’s Tech Blogs I regularly look at smart home gadgets and pet tech that make life easier for both humans and animals. In this review I’m taking a detailed look at the SiiPet Litter Lens, a cat-shaped smart camera designed to monitor your cat’s litter box habits and help you keep an eye on their health.
I’ve previously reviewed automatic litter boxes that handle the dirty work for you, and I’ll soon be featuring the Popur S7 as well. Those products are fantastic for automating the worst part of cat ownership, but they don’t always help you understand how often your cat is actually using the tray – or what their toilet habits look like over time. That’s where the SiiPet Litter Lens comes in.
For transparency, SiiPet sent me a unit of this product to review. I didn’t pay for this particular device, but this is not a sponsored post and SiiPet has no input into the content or verdict you’re reading here.
SiiPet Litter Lens Pricing and Subscription Plans
The SiiPet Litter Lens typically costs around £110, with discounts often available during major sales events.
On top of the hardware cost, there is an optional subscription that unlocks the more advanced health-tracking features:
- Free plan – Keeps around 3 days of logs, with no AI cat recognition, no stool alerts and no anomaly logs.
- $5.99 per month – Adds AI multi-cat recognition, abnormal stool alerts and anomaly logs, with roughly 3 months of history.
- $9.99 per month – Extends those features to around 12 months of history.
Pricing is broadly in line with similar camera and health tracking services from brands like Litter-Robot and Petkit, depending on which tier you compare it to. Personally, I would love to see discounted yearly subscription options, but it is worth noting that you get a free trial period to test the premium features before committing.
Key Specs: Battery, Connectivity and Core Features
The SiiPet Litter Lens is a compact, battery-powered smart camera designed to sit above or near your cat’s litter tray. On paper, SiiPet claims around one month of battery life from a full charge.
In my own usage, with two cats and the camera installed in a reasonably busy area, I saw closer to two weeks of battery life. That’s still perfectly usable, but it’s worth understanding that how long the battery lasts will depend heavily on:
- How many cats you have.
- How often they use the tray.
- How much human activity passes in front of the camera’s motion sensor.
When you do need to charge it, the device uses USB-C, which makes it easy to top up. You can also choose to leave the SiiPet Litter Lens permanently connected to power if your setup allows.
The camera connects to your home network via Wi-Fi, giving you remote access through the SiiPet app when you’re away from home. It includes:
- Motion-activated recording.
- Infrared or built-in lighting for low-light and night-time footage.
- AI-based cat recognition and behaviour detection (enhanced further with a subscription).
One nice privacy-related touch is that clips triggered by humans walking past are not stored, helping keep the focus on your cats’ activity rather than everyone moving around the house.
Cat Health Tracking and AI Behaviour Recognition
The core idea behind the SiiPet Litter Lens is to build a clear, long-term picture of your cats’ toilet habits and flag anything out of the ordinary.
The device can:
- Recognise which cat is using the litter box (with AI multi-cat recognition on paid plans).
- Record whether they actually used the litter tray or just lingered around it.
- Log visit times and build up a timetable of “normal” behaviour.
- Help identify days with unusually frequent visits, which could indicate issues such as UTIs or digestive problems.
To get the most accurate results, there’s a short training period. During roughly the first week, you’ll need to confirm in the app which cat used the tray each time. In my experience, after around three days of doing this, the AI started correctly recognising our cats consistently and continued to do so.
Over time, the app builds up a baseline for each cat, making it easier to spot patterns such as:
- A cat suddenly visiting far more often than usual.
- Less frequent visits that might indicate constipation or other issues.
- Lingering behaviour that could suggest discomfort.
The AI can also attempt to categorise what happened in each visit and, on supported plans, provide alerts for abnormalities – including stool-related alerts. In my setup, the automatic litter box I use (the Neakasa M1) has a lip on the top, which slightly obstructs the camera’s view, so the AI wasn’t perfect every single time. Even so, it managed to identify behaviour accurately often enough to be genuinely useful.
Design, Build and Installation
Design-wise, the SiiPet Litter Lens leans into its cat-focused purpose with a quirky, cat-shaped housing. The camera lens, sensors and lights are all on the front, and the overall look is quite friendly and fun compared to a generic security camera.
The unit I tested is the grey version, but there’s also a pink option if that better suits your setup.
The mounting system is flexible:
- It attaches using a strong adhesive pad, which is ideal for walls or the inside of an enclosed litter tray.
- You can also screw the mount on for a more permanent installation.
- The camera slides on and off the mount, making it easy to remove for cleaning or charging.
The base includes a channel for the USB-C cable and a rubber cover to protect the port when it’s not plugged in. The device is also designed to be washable, which is important given the environment it lives in.
For best results, SiiPet recommend installing the camera no higher than around 30 cm above your litter tray and angling it so that it captures a clear view of the area your cat actually uses.
Setting Up the SiiPet Litter Lens
Setup is handled through the SiiPet app and is straightforward:
- Download the SiiPet app and create or sign into your account.
- Pair the SiiPet Litter Lens with your Wi-Fi.
- Add your cats with names and photos to help the AI learn who is who.
- Mount the camera above or near your litter tray and adjust the angle to get a clear view.
Even with my slightly awkward test setup (the Neakasa M1 with its lip), I was able to mount the camera in a way that allowed me to test the key features. I plan to revisit this device again once I’ve had longer-term use alongside a different automatic litter box.
Everyday Use and App Experience
Day to day, the SiiPet Litter Lens works quietly in the background, monitoring your cats and sending notifications when they visit the litter tray.
In my experience:
- You’ll receive a notification once a visit has been processed by the AI.
- These notifications arrive a little later than the usage alerts from my automatic litter box, likely because the system is analysing the clip to identify both which cat was present and what they did.
- The live feed from the camera is slightly slower to load than some other smart cameras I’ve used, but for this type of product, live view speed is far less important than accurate data.
In the app’s main view, you can see:
- The camera’s live status and battery level.
- Today’s usage data for each cat.
- Whether a visit was classed as using, lingering or simply visiting the tray area.
- Any anomalies detected by the AI.
Tapping into an event lets you watch the relevant clip and, where the view is unobstructed, see exactly what happened. The AI will attempt to label the behaviour (e.g. normal visit vs something more noteworthy) and, if necessary, you can manually correct it if it misidentifies the cat or the type of visit.
There’s also a calendar view that shows long-term data. This allows you to:
- Compare activity across days and weeks.
- Identify patterns and trends over time.
- See at a glance whether things look normal or if something stands out.
The longer you use the SiiPet Litter Lens, the more valuable this historical data becomes, especially in multi-cat households or if you’re often away from home during the day.
Limitations and Quirks
No product is perfect, and there are a few limitations to be aware of.
- Battery life depends heavily on activity: With two cats and a busy placement, I saw around two weeks rather than the claimed month. If your litter area is quieter, you may get closer to the advertised figure.
- View can be affected by your litter box design: In my setup, the Neakasa M1’s top lip sometimes made it harder for the AI to see exactly what was happening. An open or differently shaped tray would likely give more accurate results.
- Not all cats are tracked equally: In my case, our black cat was occasionally missing from the stats. To be fair, he can also go outside, so the device never sees all of his activity anyway, but it’s worth being aware that AI tracking isn’t infallible.
- Subscription needed for the best features: While the free plan works, the real value is in the AI recognition, abnormal stool alerts and deeper anomaly logging – all of which live behind the subscription tiers.
Who Is the SiiPet Litter Lens For?
The SiiPet Litter Lens is particularly well suited to:
- Multi-cat households where you need to know which cat is using the litter tray.
- Cat owners who are often away from home and want reassurance about their pet’s toilet habits.
- Anyone with a cat that has a history of urinary or digestive problems where early detection is helpful.
- People already using an automatic litter box who want more insight into actual usage patterns.
Verdict: Is the SiiPet Litter Lens Worth It?
After around three weeks of real-world use, I’ve found the SiiPet Litter Lens to be a reliable and genuinely useful bit of smart pet tech.
The AI recognition is solid once you’ve gone through the initial training period, and the data it collects can be extremely helpful for spotting unusual behaviour early. For many cat owners, that peace of mind – and the ability to look back over patterns – will be worth the cost.
The main downsides are the reliance on a subscription for the full feature set, some sensitivity to where and how you mount the camera, and the fact that activity from outdoor cats will never be fully captured. Even with those caveats, it’s still a strong option if you want deeper insight into your cats’ health.
