Best litter box for Devon Rex cats

Most litter boxes are actually too big for a Devon Rex — which sounds counterintuitive, but a petite one-year-old can find a cavernous standard tray disorienting rather than inviting. On top of that, covered boxes are often a mistake with anxious or sensitive breeds: they feel trapped, smell is concentrated inside, and they'll start going elsewhere. One quick thing worth knowing: the ideal box is 1.5 times your cat's body length — for a Devon Rex that's quite modest. So — is your cat using the box at all right now, and are there any spots in the house they're avoiding or preferring instead?

That edge-perching is a classic sign the box doesn't feel right — she's trying to use it but not fully committing. At 2.5kg a Devon Rex is quite slight, and a full-size tray can feel like climbing into a bathtub. She needs something with lower sides so she can step in easily, a contained but not enclosed footprint, and no lid. What does your current box look like — is it open or covered, and roughly how big?

Right — 50cm is likely too long for her to feel settled. She needs something around 35–40cm where she can position herself centrally and feel the sides nearby without being hemmed in. My recommendation is the Savic Nestor Classic Cat Litter Tray in the smaller size — it's around 37cm long, has a low front entry edge, and open sides so she can see out and won't feel trapped. It's straightforward, easy to clean, and sized correctly for a small cat. No gimmicks. Available on Amazon UK for around £8–10. Just make sure you're filling it to about 5–6cm of litter so she can dig without hitting the bottom.

Same spot to start — she already associates that location with toileting, so changing the position and the tray at the same time can confuse things. Once she's happily using the new one for a week or two, you can nudge it gradually if you need to. Devon Rex are sharp but they can be particular about routine, so keep the transition calm and consistent. If you have more than one floor in your home, one tray per floor is worth doing too — they're small cats with small bladders and don't always want a long trek.

Perfect setup then — one cat, one floor, one correctly-sized open tray in a quiet spot. The Savic Nestor Classic small should sort the perching issue pretty quickly. Good luck with her.
