This is a specific conversation about Cat litter — what cats actually prefer — ask about yours and get one honest answer for your exact situation.

Living in a high-rise with no outdoor access means your flat essentially is your cat's entire world — and that makes odour control genuinely critical, not just a preference. The good news is that litter choice matters a lot here: cats are far more likely to use the box consistently when the texture and scent match what they naturally prefer, and most cats — Russian Blues included — favour unscented, fine-grained clumping litter over the heavily fragranced options despite what the packaging promises. Before I point you toward something specific, a couple of quick questions: is it just the one cat, are there any litter box avoidance issues at the moment, and are dust levels or tracking a concern given you're in a flat?
Just the one cat, a 3-year-old Russian Blue called Misha. No avoidance issues at all, she's very reliable with the box. Main problem is the smell — my flat isn't huge and there's nowhere to put the box that feels truly out of the way. Dust would be a bonus to reduce, and tracking is annoying but odour is the number one thing.

That's a really clean brief — reliable cat, single box, odour is the priority, dust a secondary concern. Can I ask what you're using right now? And is the smell an immediate post-use smell, or more of a lingering background ammonia smell that builds over the day?
Currently using a standard supermarket clumping litter, something like Catsan. The smell is both honestly — there's a hit when she uses it, and then a background ammonia smell that definitely builds up, especially in warm weather.

That ammonia build-up is the classic sign that the litter isn't neutralising urine odour — it's just absorbing moisture while the ammonia off-gasses into the room. Catsan is fine for absorption but it does very little active odour neutralisation. For your situation — small flat, no ventilation escape route, a cat that's reliable so you don't need to incentivise box use with anything fancy — I'd go with Breeder Celect Recycled Paper Cat Litter. It's made from recycled paper pellets that absorb liquid incredibly fast and trap ammonia compounds rather than just soaking them up. The pellets are low-dust, almost no tracking because they're too large to scatter, and critically it's completely unscented so Misha won't be put off by artificial fragrance. Russian Blues can be sensitive cats and the lack of added scent matters. The odour control is noticeably better than clay or silica alternatives for that ammonia background smell specifically. It's widely available on Amazon UK in large bags which works out cost-effective for a single cat.
That sounds promising. Will she take to the pellet texture though? She's used to fine-grain clumping. And does it clump?

Honest answer: it doesn't clump — the pellets absorb and break down rather than clumping together, which is actually why the odour control is better (no wet clumps sitting and off-gassing). Most cats transition fine, but if Misha is used to fine grain, do a gradual switch over about two weeks — mix increasing amounts of Breeder Celect in with her current litter so she adjusts to the texture. Russian Blues are generally adaptable once a box routine is established, and because she's already reliable with the box you're in a good position. The pellets are soft enough that most cats accept them without fuss. If you wanted to stay with clumping specifically, the next best option for odour control would be Oko Plus Natural Clumping Litter — also unscented, fine-grain, excellent clumping. But for a flat with a real ammonia problem, Breeder Celect is the stronger fix.
Really helpful. I'll try the gradual switch approach. Thanks.

Good luck with it — the ammonia difference should be noticeable within a few days of switching fully. One last tip: with paper pellets the used litter sits at the bottom as damp dark pellets under the dry ones on top, so scooping out solids daily and replacing the bottom layer every 5–7 days works better than the clumping routine you're used to. Once you find your rhythm with it, it's actually less work than chasing down clumps.
