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 are worth taking seriously — particularly in male cats, where a full blockage can become life-threatening within hours. Diet is one of the biggest levers you have, both for treatment and prevention. A vet check really is important if there's an active problem happening right now. To point you in the right direction, it helps to know: is your cat male or female, what symptoms are you seeing, has he been to the vet about this before, and what are you currently feeding him?
He's a 4-year-old male Maine Coon mix. He's had struvite crystals twice now, both diagnosed by the vet. He's not blocked at the moment but he does strain a bit and the vet wants him on Royal Canin Urinary SO long-term. It's really expensive and I was hoping there's a supplement I could add to his current food instead.

I understand the cost pressure — prescription urinary diets aren't cheap, especially for a big cat like a Maine Coon mix. I want to be honest with you though: for a male cat with confirmed recurrent struvite crystals, diet really is doing the heavy lifting. The urinary SO food works because it controls mineral levels and promotes a urine pH that discourages crystal formation. A supplement alone won't replicate that. What are you currently feeding him — wet food, dry, or a mix?
Mostly dry food, he gets a pouch of wet maybe every other day. I know wet food is better for urinary stuff but he's quite fussy.

That's useful to know. The dry food is genuinely the bigger concern here — it concentrates urine and creates exactly the conditions struvite crystals need. Pushing more water through his system is the single most impactful thing you can do outside of diet change. If he's fussy about wet food, a water fountain often helps a lot with cats like him. On the supplement side, the one product I'd actually recommend in your situation is Cystease by VetPlus. It contains N-acetyl glucosamine, which supports the protective lining of the bladder wall, and it has solid evidence behind it for cats with recurrent lower urinary tract issues. It won't change urine pH or dissolve crystals, but it reduces the inflammation and discomfort that comes with recurrent episodes and may reduce how often flare-ups happen. It's available on Amazon UK and it's a reasonable cost per month for a cat his size.
So you're saying Cystease is worth trying but it's not a replacement for the diet?
inparticular.ai
Exactly right. Cystease is a genuine, evidence-backed product and worth having — but it's an add-on, not a substitute. If budget is the core issue, the most effective compromise would be: switch him to a good quality wet food as his main diet rather than prescription dry, add Cystease, and get a cat water fountain to keep him well hydrated. That combination addresses the root cause — concentrated urine and mineral load — far better than supplements on top of dry food. It's also worth asking your vet whether Hills c/d Urinary Care multicare wet is an option, as it's typically cheaper than Royal Canin SO and has strong evidence for struvite specifically.
That's really helpful, thank you. I'll look into the Cystease and try to push more wet food.

Good plan. One practical tip — if he's fussy about wet food, try warming it slightly to bring out the smell, and introduce it gradually alongside what he already eats. Maine Coon mixes can be stubborn but most come round when the food smells appealing. Keep an eye on any straining or trips to the litter tray with no output — that's the warning sign that needs a vet same day, not a wait-and-see. Hope he stays comfortable.
