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 problems in cats are something to take seriously — and in male cats especially, a blocked urethra can become a genuine emergency within hours. Diet plays a huge role in both preventing and managing these issues, and I know the cost difference between supermarket food and specialist urinary diets can feel steep. That said, let me get a bit more detail so I can give you a useful answer. What symptoms has your cat been showing, has he been seen by a vet, and what are you currently feeding him?
He's a 7-year-old male Exotic Shorthair. He had a blockage about eight months ago and the vet put him on Royal Canin Urinary S/O for a while but it's expensive. He seems fine now so I was wondering if I could swap him to something cheaper from the supermarket — like Felix or Whiskas.

I completely understand the cost pressure, but I'd be doing you a disservice if I didn't tell you clearly: a previous blockage in a male cat is a big red flag for recurrence. Exotic Shorthairs are also a breed prone to urinary issues because of their flat-faced, compact build affecting organ positioning. Supermarket foods like Felix and Whiskas are not formulated to manage urinary pH or reduce struvite and oxalate crystals — the things that caused the blockage in the first place. What does your current feeding routine look like — wet food only, dry, or a mix?
Mostly dry, with a pouch of wet food in the evening. The vet had him on the Royal Canin dry urinary food but I've been mixing in some regular dry to stretch it out.

That mixing is unfortunately undermining the urinary diet — it dilutes the therapeutic effect and the pH control it provides. For a cat with his history, I'd strongly recommend keeping him on Royal Canin Veterinary Diet Urinary S/O dry food exclusively for the dry portion. I know it feels expensive upfront, but a repeat blockage typically costs £500–£1500 in emergency vet fees, sometimes more. The S/O formula acidifies urine, increases water intake through the kibble design, and dissolves struvite crystals — no supermarket food does all three. It's available on Amazon UK, often cheaper than through the vet, and you can set up a Subscribe & Save to reduce the cost further. Would it help to know how to get the most value out of a bag?
Yes actually — and should I keep giving him the wet food pouches in the evening or drop those too?

Keep the wet food — it's actually beneficial for urinary health because it adds moisture and encourages more dilute urine, which reduces crystal formation. Swap the evening pouches to Royal Canin Urinary S/O wet pouches or another vet-approved urinary wet food rather than standard pouches. For the dry, a 1.5kg bag of Royal Canin Urinary S/O on Amazon UK typically runs around £16–£18, and with Subscribe & Save you can bring that down by 15%. Given his portion size as a single indoor cat, a bag lasts a reasonable while. The peace of mind versus the alternative cost of another blockage really does make it the financially sensible choice long-term.
That makes a lot of sense when you put it that way. I'll stop mixing and get a proper bag. Thanks.

Good call — your boy will thank you for it. Stick to the S/O dry and urinary-approved wet, make sure he always has fresh water available, and ideally get a follow-up urine check with your vet every six months given his history. If you ever see him straining in the litter tray, crying, or producing very little urine, treat that as urgent and get him to a vet the same day. He's had one scare — keeping him on the right food is the best way to avoid another.
