Urinary problems in cats deserve real attention — particularly in male cats, where a blocked urethra can become life-threatening very quickly. Diet is one of the most powerful tools for prevention and management, but an active problem always warrants a vet visit first. To point you in the right direction: is your cat male or female, what symptoms are you seeing, has he seen a vet about this, and what are you currently feeding him?
He's a 7-year-old male Siamese. He gets recurrent cystitis but the vet has confirmed there are no crystals or stones — they think it's stress-related, idiopathic cystitis. He's quite an anxious cat. He's had a couple of flares this year, straining in the litter box, crying out. Currently on regular wet food, nothing specific for urinary health.

That fits a classic picture of feline idiopathic cystitis — FIC — which in anxious cats like Siamese is really common. The good news is it's very manageable once you address both sides of the problem: the urinary tract itself and the underlying stress. Before I suggest anything, a couple of quick questions — what does his environment look like, any recent changes at home? And is he an only cat or are there others in the household?
We moved house about eight months ago and he never really settled. He's the only cat but he watches the neighbourhood cats through the window and that winds him up. The vet mentioned a urinary diet but didn't specify which one.

That context is really helpful — a house move followed by territorial stress from window cats is a textbook FIC trigger for a cat like him. For a Siamese male with confirmed stress-induced cystitis and no crystals, the product I'd go straight to is Royal Canin Urinary S/O Calm. It's one of the few veterinary urinary diets that combines urinary tract support — keeping urine dilute and at the right pH — with a hydrolysed milk protein ingredient specifically included to reduce anxiety. It's not a sedative, it just takes the edge off reactivity. Given that his flares are stress-driven rather than crystal-driven, treating only the urinary side without addressing the anxiety tends to leave cats in a cycle of repeat episodes. This food tackles both in one bowl.
That sounds exactly right for him. Is it available as wet food? He's not great at drinking and I know hydration matters.
inparticular.ai
Yes, and that instinct is absolutely correct — hydration is critical for FIC cats, and wet food is significantly better than dry for keeping the bladder flushed. Royal Canin Urinary S/O Calm comes in both wet pouches and dry kibble. For a cat with his history, I'd prioritise the wet format as the main diet and use the dry sparingly if at all. You can find it on Amazon UK — search Royal Canin Urinary S/O Calm wet cat food. It's a prescription diet in some territories but is sold freely in the UK. Worth pairing with a Feliway Classic diffuser in the room where he spends most time — that environmental support alongside the diet gives you the best chance of breaking the flare cycle.
Really useful, thank you. I'll order the wet food and look into the Feliway too.

Good plan. Give it four to six weeks to see a meaningful reduction in flare frequency — the calming ingredient builds up over time. If he has another full blockage episode at any point, that's an emergency vet visit, not a wait-and-see situation. But with consistent wet food, the right diet, and some environmental calming, anxious cats like him often do really well long-term.
