Urinary problems in cats are worth taking seriously — particularly in male cats, where a full blockage can become a life-threatening emergency within hours. Diet is one of the most powerful tools for prevention and management, mainly by increasing moisture intake and keeping urine dilute and at the right pH. If there's an active problem right now, a vet check should come first. Once you have a picture of what's going on, I can help you find the most cost-effective food that actually does the job. To point you in the right direction: is your cat male or female, what symptoms are you seeing, has he been to a vet about this, and what are you currently feeding him?
He's male, eight years old, Domestic Shorthair. He's been straining a bit in the litter tray and the vet confirmed it's a urinary issue — no blockage thankfully, just crystals. Vet said to switch to a urinary wet food. I'm retired and on a fixed income so I really need the cheapest option that will genuinely work, not just something fancy. Currently feeding him a cheap supermarket dry food.

That's a really clear picture — thank you. The good news is that switching from dry to wet food alone will make a significant difference, because struvite crystals in particular are strongly linked to concentrated urine, and wet food naturally pushes hydration up. The fact that the vet has already confirmed the diagnosis and ruled out a blockage means you're in a good position to manage this with diet.
That's reassuring. So what would you actually recommend for someone watching the pennies?

For your situation, I'd go with Purina One Urinary Care Adult Cat Food — it comes in wet pouches and is consistently one of the cheapest purpose-made urinary wet foods available on Amazon UK, usually around £12 to £14 for a box of 28 pouches. That works out to under 50p per pouch, which is very reasonable for a therapeutic-grade food. It's formulated to reduce urinary pH and cut down struvite crystal formation, which is exactly what the vet has flagged. Purina One is a well-respected brand with a genuine nutritional backing — this isn't just marketing. For an 8-year-old male with confirmed crystals, one pouch twice a day alongside a constant supply of fresh water is a solid, affordable regime. If he'll tolerate it, you can also keep a water fountain running — they're cheap to buy once and encourage drinking, which compounds the benefit of the wet food.
That sounds manageable. Is there anything else I need to watch out for going forward?

The main thing is to ditch the dry food entirely, or at minimum make it a very small part of his diet. Dry food is the single biggest driver of urinary problems in cats — the low moisture content means kidneys have to work harder and urine becomes much more concentrated. At eight years old he's also entering the age range where kidney function can start to decline, so keeping him well-hydrated now is genuinely protective long-term. Watch for any return of straining, crying in the litter tray, blood in urine, or — most urgently — going to the tray repeatedly and producing nothing at all. That last one is a vet emergency. Otherwise, a recheck with your vet in a few months to see if the crystals have resolved is a sensible step, and most vets are happy to do a quick urine dip for a low fee.
Perfect, thank you. I'll order the Purina One Urinary Care pouches today.

Great choice — it's the right call for his condition and your budget. You should start to see him more comfortable in the litter tray within a couple of weeks of the switch. Good luck to him, and well done for catching this early.
