This is a specific conversation about Cat litter boxes — size, type, and placement — ask about yours and get one honest answer for your exact situation.

A self-cleaning box that broke after two months — and now your cat is refusing the replacement tray. That's a really common knock-on effect: once a cat associates a litter area with something stressful or unreliable, they start avoiding that whole spot. Worth knowing before we sort this out: most litter boxes are actually too small for adult cats — they need a tray at least 1.5 times their body length to feel comfortable using it properly. And covered boxes, while neater for us, often make cats feel trapped, especially a cat who's already a bit wary. So — how many cats do you have, how big are they, and what's the replacement tray like that they're currently refusing?
Just the one cat, she's a fairly standard-sized domestic shorthair, maybe 4kg. The replacement tray is one of those small covered ones that came with the self-cleaning unit. She's been going on the mat next to it instead.

That covered tray is almost certainly the problem. After the mechanical box made noise or moved unexpectedly — which is probably what scared her — she's now anxious about anything enclosed in that space. The cover is making it worse by removing her escape route. What litter are you using in it, and has the location changed at all since the self-cleaner was there?
Same clumping litter she's always had. Location is the same too, it's in the corner of the bathroom. I just swapped the broken unit for this small tray.

Good — litter and location consistency helps a lot. The fix here is straightforward: ditch the cover and get a properly sized open tray. At 4kg she needs something around 50–55cm long minimum. I'd get the Savic Senator Open Cat Litter Tray, the 56cm version. It's a large, no-nonsense open tray with slightly raised sides to contain scatter, no lid to trap her, and it's widely used by behaviourists for cats going through exactly this kind of litter aversion. Put it in the same bathroom spot, transfer a small scoop of the soiled litter from the mat area into it so it smells familiar, and don't move it for a few weeks. Most cats come round within a few days once the anxiety trigger — the enclosure — is removed.
Will she just start using it on her own, or do I need to do anything else to encourage her?

Mostly just let her find it herself — don't place her in it, that tends to backfire. The one thing that genuinely helps is keeping it very clean for the first week or two: scoop at least once a day. A cat who's already anxious about a litter area will write off a new tray quickly if it's not spotless. If she's still avoiding it after five or six days, it's worth trying a second tray in a slightly different spot in the same room — sometimes they want an option. But given that location and litter aren't changing, I'd expect her to settle in within a couple of days once the covered tray is gone.
That makes sense. I'll order the Savic one today and get rid of that covered tray. Thanks.

Perfect. One last thing — if you ever want to try a self-cleaning box again down the line, look for ones with very slow, quiet rake cycles rather than fast spinning mechanisms. The noise and sudden movement is what tends to spook cats. But for now, simple and open is exactly what she needs. Good luck — she should be back on track quickly.
