How can we help?

If you're not experiencing less mess and more ease with your new Luuup litter box, we've got the intel on our 3-tray perpetual shifting system. Check out our FAQ guide below that's packed with tips to help you make the most of your new purchase.

What litter works best with Luuup?

Luuup is designed to be used with clumping or crystal litter, and as feedback rolls in we have found that some brands of litters perform much better than others. We have seen the best results with Arm & Hammer Slide, World's Best Cat Litter, Mimi Litter and Pretty Litter. Based on customer feedback, we would not suggest using wheat pine, or walnut based litters, or any other litter that is not effective at clumping, as these can cause sticking issues.

It is also important to use approximately 15 lbs (or 4") of clumping litter in your Luuup, or 8 lbs of crystal litter. The depth of the litter allows it to catch waste before it reaches the surface of the tray, and the weight helps maintain the seal between layers to prevent leaking. Sifting once a day per cat using the Luuup is recommended for the best results.

Sticking Litter / Clogged Slots

Not all litters are created equal. If your litter turns into concrete and/or sticks, you're not alone (check the reviews online) We suggest Arm & Hammer Slide, World's Best Cat Litter, Mimi Litter and Pretty Litter.

It’s also very important to use enough litter to minimize sticking. The amount is far more than most people are used to adding to a box. Adding the recommended amount (approx 15 lbs of clumping litter (3-4”), or 8 lbs (2-3") of crystal litter), when combined with daily cleaning and top ups to main the level, will provide the best experience overall.

Tip: Sifting or scooping litter before wet clumps have had time to dry or set can cause them to break apart or stick with clumping litters.

Tip: If any small debris gets stuck in the slots, just press the affected tray into the litter in the box and wiggle it gently. This will work the litter up from the bottom, and remove any debris caught in the tray.

Leaking From The Bottom of the Stack

The seal in the bottom pans may have been disturbed.

Be mindful to only lift the top tray when cleaning, and keep a firm grip with both hands on the bottom two trays when stacking,and be gentle with them while stacking or moving. Disturbing the seal in the bottom pans while sifting the top tray can lead to leaking of litter between the layers.

Tip: Wiggle the Luuup while it is on the floor after cleaning to even out litter in the pan. This allows the weight of the litter in the box to keep the seal tight.

When stacked properly, your Luuup should not leak. If you're experiencing litter leaking from the bottom of your Luuup, please contact us at

My cat likes to dig to the bottom of their litter box. Would the litter box be able to deal with that?

The Luuup Litter Box requires enough litter in the box so that liquids congeal before touching the base of the tray. If your cat digs right to the bottom of the box every time, our litter system isn't suitable for your cat's needs.
