Smart Litter Boxes for Cats: Benefits and How to Choose
We independently test the products and technologies that we recommend.
1. What is a smart toilet and how does it differ from regular ones
The main advantage of an automatic toilet over regular trays is that it cleans up after the pet itself after each visit or after a set time, ensuring hygiene and cleanliness as well as odor control. It's also a great time saver for cleaning, especially if you have multiple cats. Despite its complex construction with a motor, various sensors, and a cleaning mechanism, the gadget's operation principle is simple and clear: once the cat finishes its business and leaves, the system detects its absence and starts cleaning. Clean granules of filler return to the main area, while clumps and solid waste go into a separate container or bag. Cleaning takes a few seconds to a couple of minutes.
Most modern models are a kind of house or capsule — a rather large closed design with a round or rectangular entrance. This construction helps better retain odors, but it might feel unfamiliar to the pet.
Open-type models are much rarer — they look like an upgraded tray without a lid, where the cleaning mechanism is located on the side or bottom. Such an option is simpler in design and more familiar to cats that do not like enclosed spaces.
For cleaning, toilets use either a rotating drum or rakes. In the first case, the bowl with the filler slowly rotates, excrement separates through a grid and falls into a pull-out container. In the second, special rakes pass through the filler, collecting clumps and dropping them into the container.
During cleaning, the system independently separates clumps and excrement from the clean filler and sends them to a special bag or container.
More expensive models can perform multi-step cleaning, wash reusable filler, and dry it with warm air, preparing it for further use.
There are also advanced devices that resemble a regular toilet and connect to the water supply and sewage. They are significantly more expensive, complex to install, but fully automated: after the cat uses the toilet, the system flushes the waste directly into the sewage and washes the tray without requiring any owner participation.
Most often smart toilets are connected to the mains, less often powered by a battery. Some devices can work from a battery as a backup option in case of power outages. The body is usually made of dense plastic, which does not absorb odors and is easy to clean.
2. Basic and advanced functions
First and foremost among the basic functions is automatic cleaning, without which a smart toilet loses its purpose. Equally important is odor control. The simplest option is a hermetically sealed container that keeps waste and odors inside. Devices can also use charcoal filters, built-in air fresheners that spray deodorant, and additional ventilation systems — in this case, protection against unpleasant odors will be much more effective.
In addition, the safety system plays an important role — the toilet must recognize the presence of a cat and stop any movement if it hasn't exited or enters back. Otherwise, incorrect operation may scare or even injure the animal. Budget and older models most often rely on a timer and start cleaning after a set time — 3, 5, 10 minutes, or more. This means if the pet returns, the system will still begin cleaning. A safer method is sensors: infrared, weight, or motion sensors that detect the cat's approach or presence inside the tray and do not start cleaning during this time. And if there are multiple types of these sensors, it further enhances safety. Moreover, it is advisable to have anti-pinch technologies and obstacle detection that stop cleaning if the mechanism encounters resistance or an unusual position.
Aside from the basic functions, automatic toilets may have useful additional features:
2.1 Wi-Fi and mobile application
Many modern devices connect to Wi-Fi allowing remote control through a mobile app on a smartphone or tablet. This doesn't just mean manual cleaning startup — within the app, you can view visitation statistics, receive notifications on waste container filling or errors, and set cleaning time and mode.
and receive notifications on operation and errors.
2.2 Camera
The camera serves as an additional tool for control, analytics, and safety. It doesn't operate in constant surveillance mode, turning on during visits, cleaning, or upon user request and can provide photo and video reports.
The camera fulfills several tasks. Firstly, it detects the presence of the cat and complements the operation of motion and weight sensors, which in some situations may err — for example, if the cat enters with one paw or the tray stands unevenly. Thus, the camera provides an additional level of safety and stability in the mechanism's operation. Secondly, it is necessary for monitoring the animal's behavior and habits. The camera records the visitation fact, determines how much time the cat spent inside, whether its position or behavior changed, and helps notice warning signs such as lingering in the tray too long, frequent unsuccessful attempts to go to the toilet, sharp increases or decreases in visitation frequency, unusual pre- or post-toilet behavior. Such data can be useful for early problem detection. Thirdly, the camera helps ensure the tray is clean and working correctly if the owner is not at home.
and is useful for early health problem detection.
2.3 Recognition of multiple animals
If there are several animals in the house, the toilet can distinguish them by weight or through a camera and recognition algorithms, maintaining separate statistics for each.
2.4 Weighing
Some trays are equipped with built-in scales and each time the pet enters, they determine its weight. This is useful for diet control, tracking weight gain or loss and can help notice health issues early.
2.5 Health monitoring
Smart toilets can track frequency of visits, time spent in the tray, and even intervals between toilet trips, monitor cat weight, analyze the data in a mobile app, and send helpful recommendations to pet-parents. Sharp changes in these indicators can be a warning sign and a reason to contact a veterinarian.
intervals between trips, and time spent in the tray.
Additionally, extra options include UV sterilization to reduce bacteria count, entry lighting for nighttime, and sensors signaling when the filler is running low or the waste container is full.
3. What to consider when buying
When choosing an automatic toilet, it's important to consider not only its functionality but also a number of other aspects:
- First, choose a device by size. Measure the cat's length from nose to tail base. The internal area of the toilet should be at least 1.5 times larger than the cat's length.
- The entrance diameter should suit the size of the animal — usually important for large pets.
- The height of the step (which most automatic toilets have) is also important. If you have a kitten, an elderly cat, or a breed with short legs — a high threshold may be inconvenient.
- Consider weight restrictions — exceeding the permissible load can lead to malfunctions or breakage.
- Decide on the size of the waste container — this determines how often it needs emptying. If multiple cats are in the house, it's better to choose a model with a spacious capacity.
- Listen to the gadget's operation: if it's noticeably noisy during work, it can scare animals and disturb household members.
- Consider your cat's temperament and age. If it's skittish — an open-top device, low noise level, and ability to disable sounds and indicators are suitable. For seniors and cats with mobility issues, spacious internal area and low steps are important. Moreover, smart toilets are not recommended for kittens under 6 months old and weighing less than 2 kg — sensors might not work.
4. Caveats
Along with the aforementioned advantages, although they are undeniable, there are also more or less obvious nuances that should also be considered.
- Price. The main disadvantage of smart models is the price: they cost many times more than regular trays. Even buying a budget model can be a noticeable blow to your wallet. So if you are almost always home, periodic cleaning is not a serious problem, and money is tight for an expensive purchase, it's probably better to forgo it.
- Additional expenses. Buying the toilet isn't the only cost, you'll also need to continuously purchase consumables: proprietary waste bags, filters, deodorization or sterilization cartridges. Many models are only compatible with specific fillers that match them in granule size and other parameters, and these often aren't cheap. Furthermore, it's worth checking if these consumables are readily available and if you can buy them when necessary.
- Size. Automatic toilets are significantly bulkier, taking up a lot of space, and might not suit small apartments. So, before buying, it's wise to think carefully about where the tray will stand, whether it will fit there, and if it won't get in the way.
- Care. Despite the automated process, toilets still require regular washing and care. This may be a surprise to some users hoping for the complete absence of human involvement.
- Costly repair. The device's electronics and mechanisms may fail and, in this case, be ready for expensive repairs.
- Pet refusal. It's important to understand that even the most modern toilet is useless if the cat refuses to use it, so prepare it and gradually introduce it to the new gadget. At first, don't remove the old tray, don't turn on automatic cleaning, use familiar fillers (possibly with a small amount of the old one for a familiar smell), don't force the cat inside, reward with favorite treats, and gradually acclimate to new sounds. Unfortunately, if your pet is very picky and does not accept the new tray at all — the money will be wasted.
If all the above-mentioned points don't pose serious obstacles, happy shopping!
