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

If your vet has flagged litter sensitivity as a possible cause of your Korat's eye discharge and sneezing, that's worth taking seriously — fine airborne dust from conventional litters can genuinely irritate a cat's eyes and respiratory tract, especially in breeds with more sensitive constitutions like the Korat. Litter preference matters beyond comfort too: cats are more likely to use the box consistently when the texture and scent suit them, and most cats prefer unscented, fine-grained clumping litter over scented alternatives despite what the packaging suggests. To point you toward the right option — is this your only cat, have there been any litter box avoidance issues alongside the sneezing, and are there other requirements like low-tracking or ease of disposal?
Just the one cat, Miso. No avoidance issues, he uses the box fine. The vet said to try switching litter and see if symptoms improve before doing more tests. Low-dust is the main thing, low-tracking would be a bonus.

Got it — and that's actually a sensible first step from your vet. A lot of standard clumping litters, even ones marketed as low-dust, still release fine silica or clay particles when you pour them or when Miso digs around. For a cat showing respiratory and eye symptoms, that makes a real difference. Can I ask what litter you're using now? That'll help me understand how big a switch this needs to be.
He's been on Catsan clumping litter, the standard one. We've used it since he was a kitten so I assumed it was fine, but the vet said that's not necessarily the case — sensitivities can develop.

Your vet is right — sensitivities can absolutely develop over time, and Catsan clumping is a clay-based litter that does produce measurable dust, particularly when poured or disturbed. Korats are also just a breed that can be prone to respiratory sensitivity, so it's not surprising this has surfaced at three years old. The switch I'd recommend is Cats Best Original. It's a wood-fibre litter — made from compressed plant fibres rather than clay — which means virtually no airborne dust when poured or used. It's unscented, clumps well, and because the fibres are slightly coarser than fine clay, it also tracks considerably less. It's widely recommended in situations exactly like this, and it's what I'd try first before anything more expensive or specialist. Give it four to six weeks and see whether Miso's symptoms ease. If they do, you've found your answer. If not, your vet has useful information to work with.
That sounds straightforward. Is the transition likely to be difficult — will Miso object to the change in texture?
inparticular.ai
Some cats notice immediately, others don't care at all. Since Miso doesn't have litter box avoidance issues, he's less likely to be resistant. The safest approach is to transition over about a week — start with roughly 75% old litter and 25% Cats Best, then shift the ratio gradually until you've fully replaced it. That gives him time to adjust to the different texture and smell without the box suddenly feeling unfamiliar. Cats Best has a mild woody scent that fades quickly and most cats accept it without any fuss.
Really helpful, thank you. I'll pick up a bag and give it a go.

Good luck — and do keep a note of when you switched so you can give your vet a clear timeline if you go back. Cats Best Original is available in several bag sizes on Amazon UK; I'd start with a medium bag before committing to a bulk buy, just to confirm Miso takes to it. I hope it sorts things out for him.
