Yes for all sizes. Simply install the fence or the top-entry wall and keep enough cat litter.

If your device is on the firmware 4.1.0 or a newer version, consider turning on the Curious Cat function in the Popur App, which enables two new strategies, i.e., DynaMove and ActiveShield, alongside the original Curious Cat strategy to further safeguard your small pets.

The DynaMove strategy will make sure there is zero gap between the filter and the litter bed in most cases by deciding the filter movement dynamically based on litter volume. Therefore, it’s impossible for your kittens to get under the filter. The ActiveShield strategy will retract the filter when a cat is detected, then resume the leveling process after the cat is found left. This way, it makes room for the impatient cat to use the toilet first. Needless to say, a sufficient amount of cat litter is a prerequisite for the Popur X5 to work properly. If for some reasons there is very little litter, as a precaution, in the Popur App please select the minimum two repeats for Leveling Litter, and the gap will still be less than one inch.

There is only one model at retail because we believe it is the best design. Popur debuted on Kickstarter with a plastic bin, known as the Pro model. However, we sunset it in Nov 2022 because of several quality issues occurred during production, which resulted in a poor yield rate and hence a ridiculous cost. We have re-designed the bin that consists of an automatic lid and a cardboard base. While the new design retains the merits of the original for being automatic and self-sealing, it is also outfitted with the following advantages.

● It showcases our environmental consciousness by reducing 80% of the plastics used.
● It increases the net volume to 11 liters, and the storage capacity by more than 10%.
● It requires zero maintenance by simply replacing the durable cardboard base if necessary.
● It attaches to the tray more sturdily and prevents itself from being dislocated.
● It has features to help installing the bags more tightly, as well as installing up to 5 bags together.
● It is free from any magnetic or protruded parts which might rip off a fully loaded bag.
● It is less costly.

Recently, we’ve heard the feedback that some cats cannot resist the temptations to destroy the cardboards. Therefore, we’ve designed the plastic base and cover, which works with the automatic lid included with the litter machine to form a permanent trash box. The plastic version is now available for pre-order as an add-on and will be shipped in June.

It’s actually not. The trash can is made of premium, heavy-duty cardboard that lasts three months at least. In this video, we demonstrate how tough and rugged it is, by an adult walking over and standing on it. Even the wildest cats will find it unbreakable. Some of us have used the earliest samples for over three months already, and it's still intact. The finalized material is even more durable so we can say safely that it lasts three months at least.
