Description

A prescription-level wet food for diabetic cats, formulated to help regulate blood glucose levels through a very low carbohydrate, high protein approach. Reducing dietary carbohydrates lowers post-meal glucose spikes, which can reduce insulin requirements and sometimes support remission in newly diagnosed cats.

Why your cat will benefit

  • Very low carbohydrate content, which reduces post-meal glucose spikes that are the key management challenge in feline diabetes.
  • High protein to preserve lean muscle — diabetic cats typically lose muscle mass.
  • L-carnitine to support fat metabolism.
  • Consistent formulation for predictable feeding, which matters when dosing insulin around mealtimes.

Features & specification

Important — please read before ordering

  • Consult your vet before feeding a veterinary diet. Never adjust insulin without veterinary guidance.
  • 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.

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

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

Finally, the right one

My vet recommended this food for my cat with diabetes. I didn’t get it for a long time because I wanted to try other options first. In the end, I settled on this one and hope everything continues to go smoothly. The cat stays full for longer, and I was even able to slightly reduce the amount of insulin.

Food that saved my cat!

My cat was diagnosed with diabetes in February 2024, after a month of insulin treatment her blood glucose levels were still high (around 20mmol).\n\nTowards the end of March I changed her food to the royal canin diabetic food. She loves the biscuits too!\n\nBeginning of May, she entered remission and hasn’t had to be injected with insulin since. She is still on this diet and I monitor her blood glucose once a week still and it is still in the normal range of 4.4-6.6mmol.\n\nThankyou royal canin

diabetic cat food

I was advised by my vet to feed my cat this product. I ordered it from the website and was pleased with both the price and the speed of the delivery. I will definitely re-order again soon.

Good

My cat been on this for just over a month, she likes it just wish they did more varieties. \nAlthough it's not brought her levels down as of yet I'm assuming we still need to get her insulin figured out yet.

FORMULA CHANGED SMALLER SIZE

Older reviews are for product that was of better quality than new version\nThey added more fat and God knows what else they changed, my cat doesn't want to eat it, makes him sick\nSize of packaging was Reduced significantly, but they didn't lower the price\nIt was already an expensive product and now it has been spoiled by adding more cheap fat and reducing the size\nLooks like Royal Canin is desperate for more profit.\nShame, as this food has been ruined, and my cats health deteriorated as \nB.Thanks

recommended

we tried lots of brands when our diabetic cat went off his food. our vet recommended royal canin saying most cats love this, she was right. all our cats loved it.\nVery generous portion size in each pouch, more costly than other brands but it is quality food if your budget allows. if not, there are other good brands out there, we had to try lots to get our cat eating again, now he is healthy, still diabetic, but stable.

fabulous food

My really picky 13 year old cat was diagnosed with Pancreatitis last year. He had a really tough time getting well and lost more than a kilo. This food is a god send and has been keeping his flare ups to a minimum - amazing food would highly recommend.

For post operative recovery

Following a major operation, my veterinary surgeon gave me a pack of 4 pouches of Royal Canin Veterinary Diet - Gastro Intestinal to feed my cat whilst she recovers. She is elderly and weighs just 3.2 kgs. The recommended feeding amount for this weight is 2.25 pouches per day and it is recommended that she continues with this diet for 2 - 3 weeks. My little one loves it and it's so heartening to see her enjoying her food. THANK YOU PetsZo for making it available.

Great food

If only It was rabbit or beef flavour my cat might like it better. He's so much better in this than on his iams and meat. Since the vet put him on it he's doing so much better. His coat is all fluffy and smooth again (not a shiny or silky furred cat) he no longer gets uti after uti and he is a much happier cat. Even though it takes him 4sittings to eat the stuff!
