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

Switching a 7-year-old from scented to unscented litter is exactly the right move — cats' noses are far more sensitive than ours, and scented litters often cause box avoidance precisely because the fragrance is overwhelming. The good news is that a gradual transition works well with older cats who are set in their habits. To help me point you in the right direction: is your Tonkinese currently avoiding the box, or just using it reluctantly? And are there any other requirements — dust levels, tracking, how many boxes you run?
She's using it but she does this thing where she barely steps in, does her business as fast as possible and bolts. One box, just her in the house. No dust issues flagged by the vet but she does have a sensitive stomach so I want to be careful.

That bolt behaviour is a classic sign of litter tolerance rather than litter preference — she's using it because she has to, not because she's comfortable. That actually makes the switch more straightforward: she's not fully committed to the current litter, so she's unlikely to resist a change if you handle the transition slowly. Before I give you my recommendation, what litter are you on currently — clumping clay, pellets, something else?
It's a clumping clay, scented — the pink Fresh Step one. She's been on it her whole life.

Right, so she knows clumping clay texture, which is helpful — you're only changing the scent, not the feel underfoot, and that makes a big difference. My recommendation is World's Best Cat Litter Original Unscented. It's a fine-grain clumping litter made from corn, which clumps firmly like clay so the texture won't feel alien to her, but it has zero added fragrance. It also has a very mild natural scent that cats actually find neutral or slightly appealing rather than repellent — which is the opposite of what you get with Fresh Step's perfume. Start by replacing about 25% of her box with World's Best, keep that ratio for a week, then move to 50/50, then 75%, then full switch. Because she's already semi-tolerating the current litter rather than loving it, I'd expect her to settle into the new one without much protest.
That sounds manageable. Will the corn base cause any issues given her sensitive stomach? She does occasionally groom her paws in the box.

It's a fair thing to flag. World's Best is made from whole-kernel corn and the amount a cat would ingest from paw grooming is genuinely tiny — far below any threshold that would cause a digestive reaction even in a sensitive cat. It's also widely recommended by vets for households with cats who have gastrointestinal sensitivities, precisely because there are no synthetic fragrances, chemicals or silica dust involved. If her sensitive stomach is linked to a specific corn allergy — which is rare in cats but not impossible — you'd want to check with your vet first. But for the vast majority of sensitive cats, it's actually a gentler option than the clay and fragrance combination she's on now.
No known corn allergy, the vet has never mentioned it. I'll give it a go with the gradual blend. Thanks.

Good luck with it — I think you'll notice a difference in her box behaviour within a few weeks of being fully switched. If she starts lingering a little longer before bolting, that's a good sign she's more comfortable. World's Best is available in a few sizes on Amazon UK; I'd start with the medium bag before committing to the large, just to confirm she's happy with it before you stock up.
