Description

Gravy-format of Royal Canin's Urinary S/O veterinary diet for cats with cystitis or urinary stones. Formulated to dissolve struvite crystals and reduce the conditions for both struvite and calcium oxalate stone formation.

Why your cat will benefit

  • Creates a urinary environment that dissolves struvite crystals and discourages both stone types from forming.
  • High moisture content promotes urine dilution, reducing mineral concentration and crystal growth conditions.
  • Low Relative Super Saturation for both struvite and calcium oxalate.
  • Gravy texture for cats that prefer it over loaf or jelly formats.

Features & specification

Important — please read before ordering

  • Consult your vet before feeding a veterinary diet.
  • Check-ups at least every 6 months while feeding it.
  • If your pet's health worsens, seek veterinary advice immediately.

Delivered across the UK — free delivery on orders over £59.99.

Care

General Care & Storage
To get the most out of your Petszo delivery, please keep the following in mind:

  • Edibles: Keep food and treats tightly sealed and stored in a cool, dry environment.
  • Fabrics & Beds: Gently wipe clean or wash at 30ºC (always check the individual label first). Do not bleach.
  • Safety First: Regularly check toys and accessories for damage and remove them if broken.
  • Note: Always refer to the specific packaging for exact instructions.

Getting the most out of your Petszo order comes down to storing things properly and checking them regularly. Here's what matters.

Food and treats

Keep dry food tightly sealed in a cool, dry place away from direct sunlight. Resealing the bag or transferring it to an airtight container helps stop the fats going stale, which is the usual reason a dog or cat suddenly goes off a food they previously liked.

Opened wet food should be covered and refrigerated, and used within about 24 hours. Serve it at room temperature rather than straight from the fridge — cold food is noticeably less appealing to most pets and can be harder on sensitive stomachs.

Many treat pouches contain a small oxygen absorber sachet to keep the contents fresh. This isn't edible — remove and discard it before giving your pet the treat.

Beds, blankets and fabric items

Most fabric items can be gently wiped clean or machine washed at 30°C, but always check the individual care label first — padding and covers vary between products. Don't use bleach, as residue can irritate skin and paws.

Removable covers are worth washing more often than you'd think, particularly for pets with skin sensitivities.

Toys and chews

Check toys and accessories regularly for damage, and remove anything that's cracked, split or losing pieces. Small fragments are a genuine choking and blockage risk.

Always supervise your pet with chews and rawhide products, and take away any piece small enough to be swallowed whole. Match the chew size to your pet — a chew intended for a small dog won't last long with a large one, and creates more risk.

Harnesses, collars and leads

Check the fit periodically, especially on growing puppies and kittens. As a rule you should be able to slide two fingers comfortably under any strap — tighter risks rubbing, looser risks your pet backing out of it.

Inspect stitching, buckles and clips for wear, and replace anything showing damage before it fails on a walk.

Litter trays and small pet enclosures

Scoop clumping litter daily and top up as needed; a full change every 1–2 weeks is typical, more often with several cats sharing a tray. Clean the tray itself with hot water and mild detergent rather than strong disinfectants, some of which are toxic to cats.

For small pet enclosures, spot-clean soiled bedding daily and do a full change weekly.

Switching foods

Introduce any new food gradually over roughly 7–10 days, mixing increasing amounts into the current food. Sudden changes are one of the most common causes of digestive upset, and it's easily avoided.

Always check the product packaging. The guidance here is general — individual products carry their own storage, washing and feeding instructions, and those take precedence. If you're unsure about something, or your pet has a specific health condition, speak to your vet.

Delivery

How long will my order take to arrive?

We aim to dispatch orders within 1–7 business days of you placing them. Delivery time after dispatch depends on the shipping method chosen at checkout. You'll receive tracking details by email once your order is on its way, so you can follow its progress with the carrier.

Do you offer free delivery?

Yes — delivery is free on all UK orders over £59.99. Orders below that threshold are charged at the rate shown at checkout before you pay.

Where do you deliver?

We currently deliver within the United Kingdom only. We don't ship internationally at present. Please note that a small number of items are shipped from outside the UK and may take a little longer to arrive — this is noted on the individual product page where it applies.

What if my order is late?

Carrier delays occasionally happen, particularly around public holidays or in bad weather. If your order hasn't arrived within the expected timeframe, get in touch with your order number and we'll chase it. If a package is confirmed lost or significantly delayed by the courier, we'll send a replacement or issue a refund.

How do I track my order?

Once your order ships, we email you tracking details. Use these to check live delivery status directly with the carrier.

Returns & refunds

Can I return something if I change my mind?

Yes. Under UK consumer law you have 14 days from receiving your order to tell us you'd like to cancel, and a further 14 days to send the items back. Items need to be unused, in their original packaging and in the condition you received them. Return postage for change-of-mind returns is at your cost. Full details are in our Refund & Return Policy.

What if my order arrives damaged or incorrect?

We'll put it right. Under UK law you have up to 30 days to reject a faulty item for a full refund. For transit damage, contact us ideally within 48 hours of delivery with photos of both the item and the packaging. We cover return postage on faulty or incorrect items and will offer a full refund or a replacement.

Are there items I can't return?

For hygiene and safety reasons, opened or unsealed pet food and treats, used grooming products, personalised items and gift cards can't be returned unless they're faulty.

How long do refunds take?

Once we've received and inspected your return, we'll let you know whether it's approved. Approved refunds are processed within 14 days of us receiving the goods, back to your original payment method.

Can I cancel an order before it ships?

Yes — email support@petszo.co.uk with your order number any time before dispatch. If it's already gone out, you can return it under the 14-day change-of-mind period once it arrives.

Products

Do I need a prescription for veterinary diets?

No prescription is legally required in the UK to buy veterinary diet foods. However, these products are formulated for diagnosed conditions, so we strongly recommend speaking to your vet before starting one — and having your pet checked at least every six months while feeding it. If your pet's health worsens, seek veterinary advice straight away.

How should I switch my pet to a new food?

Gradually, over roughly 7–10 days. Mix a small amount of the new food into the current one and increase the proportion each day. Switching abruptly is a common cause of digestive upset.

How do I store pet food once it's open?

Keep dry food in a cool, dry place, ideally resealed or in an airtight container to stop the fats going stale. Opened wet food should go in the fridge and be used within about 24 hours. Always check the individual packaging, as some products have specific requirements.

Shipping & Returns

Last updated: 16 August 2026

This policy explains how we process, dispatch and deliver orders, and what to do if something goes wrong.

1. Delivery charges

Delivery is free on all UK orders over £59.99. For orders below that value, the delivery charge is calculated and shown at checkout before you complete your purchase — you'll never be charged an amount you haven't seen first.

2. Order processing and dispatch

We aim to dispatch orders within 1–7 business days of the order being placed. Business days are Monday to Friday, excluding UK public holidays.

Once your order has been processed you'll receive a confirmation email, followed by tracking details where available.

5. Tracking your order

Once your order ships, we'll email you tracking information where available. You can use this to check the live delivery status directly with the carrier.

Some delays are outside our control — carrier backlogs, severe weather, and public holidays being the most common. If your order hasn't arrived within the expected timeframe, please contact us with your order number and we'll investigate.

If a package is confirmed lost or significantly delayed by the courier, we will send a replacement or issue a refund.

7. Incorrect delivery addresses

Please check your delivery address carefully at checkout. If you spot a mistake, contact us immediately — we can usually correct it before dispatch. Once an order has shipped to an address you provided, we may not be able to recover it.

Fantastic Product

This food is totally worth the price. My 6 year old boy was very poorly with a snowstorm of struvite crystals in his bladder. He was catheterised and he faced a very expensive, very painful operation with which success wasn’t guaranteed or I had to face putting him to sleep as his quality of life at this point was nil. He was sent home with three days worth of these pouches. During this time he improved and now after 5 weeks his bladder is back to how it should be. He is my happy, boy once again

Saved my cats life

My cat was having constant issues with blood in urine and not being able to pee, to the point where he was in every few days to get his bladder drained and on expensive medication which did nothing, the vets didn't know what else to do and the prospect of euthanasia was brought up, he was already on a urinary care food from another brand but as a last ditch effort we decided to try this, since then my cat has had no issues with blood or difficulty peeing and is even off all medication!!

Urinary S/O brilliant

I was worried because my cat had to be on this product by my vet. And i wasn't sure if he would eat it. I shouldn't have worried as he took to it immediately. \nHe was on it for 3 months to completely get rid of the stones he had in his urine. \nNow he is on normal royal canin urinary and British short hair and sterilised, which supports urinary health.

Lauren
Royal Canine urinary S/O

My vet recommended this after my cat had a urinary blockage, he seems to really like the food, looks good quality and always clears the bowl. Does its job and I 100% recommend, also works best alongside feliway Cystease if advised to use it.

Urinary food

Brilliant, was fast delivering and just what I needed. Cat loves it which I’m so glad about because I was worried about starting his special diet. Pieces are nice and small easy for him to chew. I recommend this food to anyone whose cat has to be on a urinary diet.

Changed ?

My cat has been on this food and the dry for around 8 years with no issues at all. However after the latest purchase he will lick the gravel off but not touch the meat at all - I have had to change him to a different brand and now have three and a half boxes of this expensive food going to waste

Recipe change

My cat used to love this however they have changed the recipe and he is allergic to whatever the new ingredient is. Multiple vet trips confirmed the source of his itching was in fact his food. This recipe change wasn't advertised on any of the boxes, really disappointing since I am struggling to find another urinary food he likes.

the product is fine the delivery was delayed and when we recieved it the box was damp and a bit battered upon opening i found 36 loose royal canin vetinary pouches scattered in the box and 1 full box was it sent like this ? always had very good service and the product is fine but storing 36 loose pouches was fun

Recipe Change?

Bought the Morsels in Gravy a number of times and my cat absolutely loved it. The last pack however is different and she will not touch it similar to a few reviews below. I noticed changes in the smell, texture and the consistency of the gravy with this last batch.

Bad batch?

My cat initially LOVED this food, but he has refused to eat the last two batches I have bought. I now have almost a 100 sachets of food he is refusing to eat!

My cat wouldn't touch it

My senior cat loves eating the dry food version of this product but for some reason, he wouldn't touch the wet food. Clearly they are not the same thing. More money wasted! But at least, some of the aging fur babies in Cats Protection adoption center can be benefitted from the remaining pouches.

Our puss was diagnosed with bladder crystals last year and has been on this and also the dry food since diagnosis. \nHis health has improved and no longer has issues witthe cystals but the vet recommended he stayed on this food. Now, our boy is a fussy pussy- likes a change, a treat so we were dreading the prospect of him turning hisn ose up at this. Oh no, how wrong were we. He loves this and looks so well.

S
Sandra
Surprisingly good

Having a fussy eater I was concerned when advised to feed this for his urinary problems but he loves it, never turns his nose up now. He also loves the less calorie wet food and the dry food

Cats enjoy this

This is a specialist urinary S0 food, our cats love it and one of them had struvite crystals in the urine and therefore kept getting infections, whilst she does still have infections they have reduced usually while being on this food.\nThe cats do enjoy eating this food it’s just a shame there is not a wider choice of flavours, there is currently just one.

Product is ok

Product is ok my cat will eat it but don't think she loves it a lot but health has improved. Now buy from other place in larger box though as it is amongst the most expensive place to buy it from here

No more cystitis

Amazing product. My cat had cystitis several times over a few months for no apparent reason. In the end she developed bladder stones the infection got so bad (she is a nightmare to get antibiotics into and the injection antibiotics didnt work). Vet recommended this food and after a couple days of not giving her the beloved felix she loves it and hasn’t had cystitis for over a year! Definitely recommend. She is now on it permanently combined with the low cal biscuits and she couldn’t be happier.

Happy Cat = Happy Cat Mum!

Our tabby suffers massively with anxiety causing him to have urinary issues like cystitis. First of all my cat (Genie) can not get enough of both the dry and wet food, he loves it and find him waiting for his meals! Second of all, his health has massively improved! Toilet time is much easier and often and find myself finally feeling less worried. My vet reccomended this food and I will 100% stick with it! Happy 😊

Kipper

My cat used to love the old recipe with chicken but this new recipe she does not like and I want to change the food now so need to speak to the vet to see if you offer something similar. The picture on the food has changed as well. I have tried this new recipe for a couple of months.

Won’t eat

This got recommended by my vet alongside the dry mix as well. She loves the dry food but will not touch the wet - tried to mix with tuna but still turns her nose up :(

Happy kitty

My boy loves this food, only because he doesn't know that it's good for him
