Explainers
These 7 are the questions that come back month after month in owner discussion, from kittens to drawer arithmetic, and each one leads with a short answer.
Every automatic box waits until a sensor says the cat has left, then separates clumped waste from clean litter and puts it somewhere sealed. Drums turn the whole chamber over a screen; open-tops do it under an open rim; rakes comb a flat bed; crystal-tray boxes rake a disposable tray; flushing boxes wash waste down a drain. The mechanism decides which litter you can use and whether you buy a consumable every month.
Read the full answer →Not until the kitten is heavier than the box's minimum detection weight, and old enough for the maker's own age rule. Published thresholds here run from 2.2 lb to 3.5 lb, which at roughly a pound a month means somewhere between three and six months depending on the box. Until then, run the box in manual or kitten mode and clean it yourself.
Read the full answer →Divide the drawer's volume in litres by 0.7 for each cat. A 10-litre drawer lasts about two weeks with one cat and one week with two. 6 of the 20 makers that publish both a volume and a one-cat claim say their drawer lasts more than a quarter longer than that.
Read the full answer →Drums, rakes and open-tops need clumping litter; most are designed around clay and many reject pellets. 12 boxes here list tofu as compatible and 12 rule it out. Crystal-tray and flushing boxes take only their maker's own consumable.
Read the full answer →Slowly, and with the box switched off at first. Put it where the old box was, keep the old one nearby for a while, add a scoop of used litter, and only turn automatic cleaning on once the cat is using it. Set the longest cycle delay so the machine never moves while the cat is close.
Read the full answer →Less than with a normal box, but not nothing. Empty the drawer, top up litter as the level drops, change carbon filters or deodorisers every few weeks, and take the box apart for a full clean every one to three months. The makers' own intervals are below.
Read the full answer →Sensors and connectivity cause more trouble than motors. Weight readings drift, drawer-full indicators misread, and apps lose the box. Standard warranties are short: 20 boxes here come with one year and 11 with two or more.
