This is a specific conversation about Cat urinary problems — diet and products that help — ask about yours and get one honest answer for your exact situation.

Urinary issues in cats deserve real attention — particularly in male cats, where a blockage can turn life-threatening within hours. Diet is one of the biggest levers you have for prevention and long-term management, and struvite crystals specifically are very responsive to what your cat eats. A vet check is essential if there's an active problem. To give you the most useful advice: is your cat male or female, what symptoms are you seeing right now, has he been seen by a vet about this, and what are you currently feeding him?
He's a 5-year-old male Domestic Longhair. He had struvite crystals diagnosed about a year ago — the vet sorted him out and said to keep him on wet food. I've been buying the own-brand wet food from the supermarket to save money. He seems okay but I want to make sure I'm doing enough.

Good that he's stable — and you're right to question it. Generic supermarket wet food is better than dry food for urinary health because the moisture helps, but it doesn't actively manage struvite. Those foods aren't formulated to control urinary pH or mineral levels. For a male cat with a confirmed struvite history, that's a meaningful gap. The moisture alone isn't doing enough work. What does a typical week of feeding look like — how many pouches or tins, and roughly what are you spending?
Usually about two pouches a day, sometimes three. I'm probably spending around £15 to £20 a month on food. I can go a bit higher if it actually makes a difference but I don't want to spend a fortune on prescription stuff.

That's a completely reasonable position. Here's the one product I'd point you to: Royal Canin Veterinary Urinary S/O wet food in pouches. It's not a prescription item — you can buy it on Amazon UK without a vet script — and it's specifically formulated to dissolve struvite crystals and keep urine dilute and at the right pH to prevent reformation. For a male cat with your boy's history, it's the most evidence-backed non-prescription option available. A 48-pouch box runs around £35 to £40 on Amazon, which works out to roughly £22 to £25 a month at two pouches a day — not far off what you're spending now, and doing genuinely targeted work instead of just providing moisture. Given that a urinary blockage in a male cat can mean an emergency vet bill of several hundred pounds, it's a strong investment.
That's not as expensive as I expected. Is it okay to mix it with some of the regular food to make it go further, or does it have to be fed exclusively?
inparticular.ai
Royal Canin recommend feeding the Urinary S/O exclusively for it to work properly — the pH control and mineral balance depend on it making up the whole diet. Diluting it with regular food undermines the formulation. That said, if budget is genuinely tight some months, feeding it exclusively five or six days a week and having one or two days on a good-quality non-urinary wet food is far better than splitting every meal. Just avoid dry food entirely given his history — that's non-negotiable for a male cat who's already had struvite crystals. Keep his water bowl topped up and consider a cat fountain if he's not a big drinker, as hydration is doing real work here too.
Really helpful, thank you. I'll order the Royal Canin and keep it as his main food.
inparticular.ai
That's exactly the right call. Stick with it as his staple, keep water available at all times, and watch for any signs — straining, frequent trips to the litter tray, crying, or blood-tinged urine — as reasons to go straight to the vet rather than wait. With his history under control and the right food in place, you're in a genuinely good position.
