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.

Your vet is giving you good tools — home pH monitoring is genuinely useful for male cats with urinary history, and a Manx at six years old is exactly the kind of cat where staying on top of this matters. Urinary issues in male cats can escalate quickly, so the fact that you're being proactive is the right move. To help with the dietary side, tell me: what is he currently eating — wet, dry, or both — and do you know whether his issue has been struvite crystals, calcium oxalate, or something else? And has the vet put any specific dietary restrictions in place yet?
He's been on dry food most of his life, Royal Canin Adult. The vet said he had struvite crystals and his pH was running high — around 7.5. They recommended the pH strips to track it at home and said to look at a urinary diet, but didn't prescribe one specifically. No other restrictions mentioned.

That's a clear picture — struvite crystals form in alkaline urine, so the high pH explains exactly what's happening. The good news is struvite is very responsive to diet. The main goals are acidifying the urine to bring pH down to around 6.0–6.5, increasing moisture intake, and reducing magnesium and phosphorus. Dry food is the harder part here — it contributes to concentrated urine, which is a problem for male cats generally. Has he ever eaten wet food, or is dry all he's known?
He'll eat wet food if I give it to him but I've always defaulted to dry because it's easier. I'd be willing to switch or do a mix if it helps.

A mix is a solid starting point, and honestly for a male cat with a struvite history it's one of the best things you can do. More wet food means more water through his diet, which dilutes urine and reduces crystal formation. For the actual urinary management, I'd recommend Royal Canin Urinary Care wet food in pouches — it's formulated specifically to support a healthy urinary pH, reduce struvite risk, and encourage water intake. It's not a prescription diet, so you don't need a script to buy it, but it's built around the same principles. Use it as the base of his meals and you can supplement with a smaller amount of a quality dry food if he needs the variety. The pH strips your vet recommended will tell you within a week or two whether it's working — you're aiming for that 6.0–6.5 range.
That makes sense. Which pH strips should I be using — the vet mentioned them but didn't say a specific brand.

For cat urine pH, you want strips with a range of roughly 5.0–8.0 and small enough increments to be useful — 0.5 pH steps is ideal. Valertest Urine pH Test Strips are available on Amazon UK and work well for this purpose. Collect a small sample when he uses an empty, clean litter tray — rinse it and let it dry first so there's no residue affecting the reading. Test in the morning if you can, as that's when urine tends to be most concentrated and gives you the most consistent baseline. Once he's settled on the new diet, testing a couple of times a week is usually enough to keep an eye on trends.
Perfect, that's exactly what I needed. I'll switch him over to the Royal Canin Urinary Care wet food and get those strips ordered.

Good plan. Transition the food gradually over about a week — mix increasing amounts of the new food with what he's used to so you don't upset his digestion. If his pH doesn't come down into range within two to three weeks on the new diet, or if you see any signs of straining, crying in the litter tray, or blood in his urine, go straight back to the vet. Male cats can block fast and it becomes an emergency quickly. But with consistent monitoring and the dietary change, you're in a strong position to keep this managed.
