Two cats means twice the scooping, and a shared box that gets dirty fast. A self-cleaning litter box for multiple cats fixes the daily part of that problem: LitterLux sifts after every visit, so the second cat always steps into clean litter, and waste is sealed away in a 9L drawer instead of sitting in an open tray.
Built for two-cat homes
- Capacity. A 65L drum and 9L waste drawer give two cats room to go and room to fill. Expect to empty the drawer more often than a one-cat home would, roughly every week depending on litter and diet.
- Cleans between visits. The cycle runs after each cat leaves, which matters when cats are fussy about using a box another cat just used.
- Weight tracking per visit. The weight sensor logs each visit in the Tuya app. If your two cats are different sizes, you can usually tell their visits apart.
- Safe when cats crowd around. A 120-degree infrared sensor and the weight sensor pause the cycle if either cat approaches or gets in.
How many litter boxes do multiple cats need?
The common rule is one box per cat plus one extra. In practice, many two-cat homes do well with one self-cleaning box because it is always clean, but a second regular tray is a good backup, especially while the cats are getting used to the new box. LitterLux is rated for up to two cats weighing 1–8 kg (about 2.2–17.6 lb). If you have three or more cats, plan on a second unit.

Keeping a multi-cat box fresh
- Empty the drawer when the app says so. The full-drawer alert takes the guesswork out of it. Keep litter bags on hand.
- Change the filter on schedule. Two cats work a filter harder; a 3-pack of replacement filters covers you for months.
- Top up litter. Clumping bentonite, tofu, crystal or mineral litter all work. Avoid pellet and strip litters.
- Deep clean monthly. The drum and drawer come apart without tools. Our cleaning routine guide has the schedule.
Multi-cat FAQ
Will both cats accept it? Usually yes, but introduce it next to the old box and let the braver cat go first. Our transition guide covers the details.
What about the smell with two cats? Plasma sterilization, a fresh-air system and a sealed drawer do most of the work. See our odor control litter box page.
What if one cat is big? The 8 kg limit is per cat. For larger breeds, read our page on automatic litter boxes for large cats.
