Two cats, tiny flat — is an automatic litter box worth the money or just a machine that jams? Cat

Numbers from my last twelve months, two cats, one auto box: litter went from roughly 18 kg a month in a manual tray to 11 kg because I stopped throwing out half-clean litter every time I did a full change. Liners are the hidden cost — I use compostable bin bags instead of branded liners and the fit is fine. The machine paid for itself somewhere around month sixteen on litter alone, which is slower than the marketing suggests but not nothing.

I have owned three of these across about seven years and I regret two of them. The two I regret were both the rake-through-a-flat-tray design — anything softer than a perfect clump smears, and then you are cleaning a machine instead of a box. The globe-style one has been fine for two years with the one caveat that my larger cat needed a month of the lid staying open before he would use it. If you buy one, buy the design where waste falls into a lined drawer, not the kind that drags a comb across the litter bed.

Gently disagreeing with the framing rather than the machine. I bought one for the same reason you are considering one, resented scooping, and what actually fixed it was a second tray. Two boxes in a small flat meant neither filled up in a day, so scooping became a thirty-second job I stopped noticing. That was about $40 and no electricity in a windowless bathroom.

Six weeks in as a first-time owner of one. Transition was slower than I expected — one cat took four days, the other took nearly three weeks and needed the cycle timer pushed out so it wasn't running right after she left. Noise is a low grinding whir for about ninety seconds, which in a windowless bathroom with the door shut is genuinely fine, but I would not want it in a bedroom.

Odour depends more on the drawer seal than the brand. Mine has a carbon filter slot that does very little and a rubber gasket that does almost everything, and once the gasket went hard at about eighteen months the whole bathroom knew. Replacement gasket was cheap and available, which is the thing I would check before buying: can you get seals and a drawer lid five years from now, or is it a sealed appliance?

One practical thing nobody mentions: weight sensors. Mine reweighs after every use, and when the flat gets cold the plastic contracts enough that the sensor drifts and it starts logging phantom visits. Recalibrating takes a minute but if you plan to rely on the weight-tracking as a health signal, know that it is noisy.
