Neakasa M1 Plus (automatic litter box the open litter box for large cats): our review

A cat that likes a clear view of the room while using the litter box has a reason to favor this open design. The M1 Plus pairs that familiar arrangement with an XXL format intended for large cats. The manufacturer sets a maximum cat weight of 15 kg, so larger cats belong within its intended range. That limit still needs to fit the cat coming through the entrance.

Does your cat already choose an uncovered tray over an enclosed box? We like the open format for cats with that established preference. There is less change in the basic arrangement, even though the appliance itself will be unfamiliar.

In an apartment where the litter box shares the bathroom, the exposed litter area will remain visible. Your cat has probably never worried about matching the towels. For you, the useful balance is a layout your cat accepts and a permanent spot you can reach easily for maintenance.

The waste bin holds 11,23 L, giving collected waste more room and potentially spacing out trips to empty it. Coming home from a weekend away, that extra room could make the return to household chores less abrupt. A bigger drawer offers breathing room, not a deadline. The number of cats using the box and the litter used will determine how quickly collected waste fills it.

The litter tray holds 7,17 L, providing a separate supply for your cat's visits. Keep an eye on that supply as well as the waste bin. More space for used litter does not refill the clean litter your cat needs.

Waste bin capacity ranks among the best on the site, and that strength matters if emptying is the chore you most want to space out. The removable bin also lets you take the collected waste out directly. Standard trash bag compatibility keeps that part of the routine familiar: leave replacement bags within reach, particularly when a neighbor is stopping by to feed your cat during vacation.

An airtight waste compartment is the odor control feature here. It is designed to contain odors from collected waste, a useful distinction when the litter box sits near a doorway guests pass on their way inside. The open litter area still needs ordinary attention. Containing waste below does not remove the need to empty the bin and clean the parts above.

The detachable globe gives you a removable component for more thorough cleaning. Before choosing that laundry room corner, think through where the component will go during maintenance and how you will carry the filled waste bag out. A reachable location can make a recurring chore less awkward.

The unit weighs 10,35 kg, a typical weight that calls for both hands when carrying. Its weight is well placed in our assessments, but moving the appliance is still something to plan around. Keep it somewhere you can maintain it comfortably without repeatedly shifting the whole unit. Convenience starts with where you put it.

A visit counter gives you a record of how often the litter box gets used. If your cat usually heads toward the tray after dinner, a change in that familiar pattern may prompt a useful conversation with a veterinarian. A visit count cannot explain a change in habits or assess health. It records activity; interpreting that activity belongs elsewhere.

Presence detection is the manufacturer's advertised safety feature. The manufacturer says the unit detects a cat's presence, but that claim is not a guarantee of safety. Give your cat time to get used to the box before making it part of the daily routine.

Manufacturer instructions recommend a gradual transition, initially leaving the unit switched off or in manual mode for a few days with the previous litter box beside it. Give your cat room to approach at its own pace. The goal is a familiar daily routine with less scooping, and rushing the introduction does little to help either of you get there.

The entry threshold is 35,2 cm, a high step that a senior or stiff cat may find harder to cross. How comfortably does your cat get into its current tray? Watch the whole movement: hesitation, awkward footing, or a laborious climb matters more than whether your cat falls within the maximum weight limit.

UBPet C41 is better suited to a senior cat thanks to a lower entry threshold of 20,3 cm. We would consider UBPet C41 for easier access when getting into the box comfortably matters more than room for collected waste.

UBPet C41 has a lower waste bin capacity at 6,7 L, which means less room before the drawer fills. UBPet C41 is less well rated overall. That does not undo its practical advantage for a cat with stiff legs. Our preference here follows daily access: the Plus design makes more sense for a mobile cat that can enter comfortably and already favors an open tray.
