Ocicat urinary health: diet and products that help

Urinary issues in cats are worth taking seriously — and in male cats especially, a blocked urethra can become life-threatening within hours. Diet is one of the most powerful tools for prevention and management. If your cat is showing active symptoms like straining, crying in the litter box, or producing little to no urine, a vet visit should come first. That said, it sounds like you're in a good position: you know your Ocicat is prone to this and you want to get ahead of it. Can you tell me — is he showing any symptoms at the moment, has he been vet-checked recently, and what are you currently feeding him?

Good — no active symptoms and a recent vet check is the best possible starting point. The issue with supermarket dry kibble is twofold: it's low in moisture, which concentrates urine and raises the risk of crystal formation, and many formulas are higher in minerals like magnesium that can contribute to struvite crystals. Male cats already have a narrower urethra than females, so what would just be uncomfortable in a female can become a blockage in a male. Ocicats specifically have a reputation for urinary sensitivity. The single most impactful change you can make right now is switching from dry to wet food — that alone significantly increases your cat's daily water intake. Can I ask: is he currently drinking from a bowl, a fountain, or both? And is he on any particular flavour or protein preference, or is he eating whatever you put in front of him?

That low water intake is exactly what you want to address, and switching to wet food is the most effective way to do it passively — cats get most of their hydration through prey in the wild, so wet food is far closer to how they're designed to eat. Given that he has no diagnosed condition, just a breed-level predisposition, you don't necessarily need a prescription diet yet. What I'd recommend as your first move is Royal Canin Urinary Care wet food in gravy pouches. It's formulated to dilute urine, reduce the concentration of minerals that form crystals, and maintain a urinary pH that discourages both struvite and calcium oxalate crystals. It's not a prescription product, so you can buy it on Amazon UK without a vet referral. Because your cat isn't fussy, the transition should be easy — just phase out the dry kibble over about a week. I'd also suggest adding a cat water fountain alongside this; cats are often more drawn to moving water, and it'll complement the dietary change well.

You don't need a vet visit before making this switch — it's a supportive diet, not a medical intervention, and it's appropriate for healthy cats with a predisposition. Mixing wet and dry is fine during the transition, but ideally you'd move to predominantly wet food long-term, with dry making up no more than about 20% of his intake if you keep it at all. If you do keep some dry in rotation, look for one that's lower in magnesium and ash content — but honestly, for an Ocicat with your concerns, going fully wet is the cleaner solution. Once he's fully transitioned, keep an eye on his litter box habits: good urine output, no straining, no crying. If anything changes, that's your cue for a vet check. A follow-up urinalysis once a year isn't a bad idea for a breed-prone cat either — worth mentioning at his next routine appointment.

That's a solid plan — those two changes together will make a real difference. For the fountain, the Drinkwell Pagoda or the PetSafe Drinkwell 360 are both well-regarded and easy to clean, which matters for keeping the water fresh. The main thing is just to keep the fountain topped up and cleaned weekly so he actually uses it. You're already ahead of most first-time owners by knowing the risk — catching this before there's a problem is exactly the right approach.
