Cat litter box safe from rabbits

A rabbit nosing around the cat's litter box is a surprisingly common problem when they share a space — and it's worth solving properly, because rabbits can pick up toxoplasmosis from cat faeces, and honestly it's just not a habit you want to encourage. Before I get into options: self-cleaning litter boxes genuinely do reduce daily scooping and keep things fresher, which helps cats use the box consistently — but they're expensive, need specific litter, and some cats take time to accept them. A secure lid design might actually solve your problem more simply. Can I ask — is this one cat, and is the main goal just stopping the rabbit getting in, or are you also dealing with the cat being fussy about the box?

That's helpful — if the cat's already happy with its box, you don't need to overthink this. What's the rabbit's setup like in the room? Is it free-roaming most of the day, or just out for supervised periods? And roughly what's your budget — are we talking under £30, or are you open to spending a bit more for something really solid?

Right, so with a free-roaming rabbit you need something the cat can get into easily but the rabbit physically can't — and the best solution for that is a top-entry litter box. The Savic Hop In is my clear recommendation here. It's a sturdy enclosed box with a hole in the lid that cats jump down through — rabbits can't jump up and through in the same way, and even if they get on top, the opening is designed so they'd just sit on the lid rather than fall in. It's well within your budget at around £25–30, it's robust enough that a rabbit bumping into it won't knock it over, and most cats adapt to top-entry boxes quickly since they naturally like the enclosed feel. The only caveat: if your cat is elderly or has mobility issues, top-entry isn't ideal — but for a healthy cat it's a genuinely neat fix.

The Savic Hop In has a textured grid on the lid that catches a fair amount of litter as the cat climbs out — it's not perfect, but it's noticeably better than a standard open box. If you find litter scatter is still an issue after a week or two, a cheap litter-trapping mat placed underneath the lid opening sorts it completely. Most people find the built-in grid does most of the work though. It also takes any standard clumping litter, so no need to switch what you're already using.

Great choice — it's one of those simple solutions that actually works. Worth introducing it alongside the old box for a few days if you can, just so the cat gets used to the new entry style before you remove the original. Most cats figure it out within a day or two. Good luck with the rabbit too — they're relentless little explorers.
