Product description
Dietetic wet food for cats with urinary tract problems, helps to dissolve struvite stones, increases the volume of urine & promotes a healthy urinary tract, low in magnesium, contains urine acidifiers
General information:
- Please seek your vet's advice before using this food or extending the feeding period.
- When feeding your cat with a veterinary diet you should consult your vet regularly for check-ups.
- If your cat's health deteriorates please seek veterinary advice immediately.

Royal Canin Urinary S/O Diet is specially formulated to specifically support the treatment of cystitis and urinary stones. This food can help to dissolve painful struvite stones and crystals as well as calcium oxalate stones. It simultaneously works to prevent new stones from building up and reduces the risk of cystitis. The special ingredients increase the volume of urine and optimise the RSS value. The recipe also ensures that your cat receives all the vital nutrients it requires for a healthy immune system.

Royal Canin Veterinary Cat - Urinary S/O contains the urine acidifiers calcium sulphate and DL-Methionine. It is also low in minerals, which makes it harder for crystals to form. The increase in the volume of urine means that it is thinner, and the urinary system is flushed out more. This wet food therefore helps to keep the urinary tract healthy. You can support your cat’s health while also giving it a tender and tasty meaty meal. This high-quality dietetic food is recommended by vets and can help cats with urinary tract problems to live an active and happy life in the long term!

- Effective against struvite and calcium oxalate stones: can dissolve stones and crystals and reduce the risk of new ones forming

Torn...
Im torn on this product, it seems to keep my cat well, he hasnt had any crystals in over a year whilst on this (plus a multi cat household biscuits) so thats a plus. I changed from the bits in gravy to the loaf as he would eat the sauce and leave the rest, he isnt a fan of the loaf (negative) but if i add a bit of hairball paste (also sold here) and mash it all together the will happily eat the lot. I dont much like the fact it is expensive, and maybe it could come in varied flavours....

Cat dislikes
I'm new to this product as my cat has been put on this diet by her our vet due to formation of crystals in her urine. She doesnt like it at all. During transitioning her she leaves all of it. Shame there's none in jelly as she wont eat anything in the so called "gravy".

My Cat loves this
This is really great for my cat who has a urinary problem that needed hospitalisation, he's made a full recovery and has been well for over a year now on this diet..

My cat loves it
My 1 year old Harry has recently been put onto this food following two blockages. He absolutely loves it, licks the bowl completely clean every day. So far he's had no reoccurrence of his illness so we're really hopeful the food is working for him. The alternative was a really invasive operation so we're thrilled that it seems to be working!

dont order
a costly mistake i clicked on wrong item. my cat will not eat its solid, dry and you cant even break it up with a fork. it also does not smell very nice yuk on all fronts

Not loaf in sauce
The product has changed as last 2 boxes I ordered were more like pate, not small lumps in sauce anymore. Zooplus needs to remove the 'in sauce' wording from their product description (I have queried this with them). Cat won't touch it.

Cats really hate it. Cat repellent.
Both my cats hate this food. They ran away from the dish when I put it near- the smell is foul to them.
I bought 4 x boxes of 12 :(

Great something he will eat and like
My cat has to have the special wet diet and did have the cans until they discontinued. he loves this wet food, especially as it seems to have more gravy - so pleased 😃

Wet mud texture - no clear flavour - unappealing - cat dislikes it.
Royal Canin have not only reduced the pouch sizes but now they have messed with the content as well. No idea what flavours are as they are just described as 'loaf' or 'strips'. Last monthly order for my cat I thought I would try the 'Loaf', imagining something with some consistency & visible solid bits of 'meat' in it. Instead of that, what slithers out of the pouch is some brown thing with a tiny bit of thickish 'gravy'. Turns to moosh if you try to cut it into more manageable cubes. Rank!

Best of the Range
This is the only Urinary S/O from Royal Canin that my cat will eat.

Less for your money
The quality of this food is great on my cats tummies. But very disappointed they’ve changed packaging, product and the quantity 100g to now 85g
The last time I’ll buying anymore of this.
Pure principle really.
