Description

Neutering slows a cat's metabolism while appetite often stays the same — which is the usual route to steady weight gain. Purizon Sterilised cuts fat to 11%, against 20% in the standard Adult recipe, and adds DL-methionine for urinary health.

Why your cat will love it

  • 46% protein with 70% carefully selected meat and fish
  • Reduced fat at 11% — against 20% in standard Purizon Adult
  • DL-methionine helps lower urinary pH, reducing the risk of struvite stones
  • 30% fruit, vegetables and herbs for natural vitamins and fibre
  • Grain-free and gluten-free

Features & specification

  • Sizes: 400g, 2kg (5 x 400g) and 6.5kg
  • Life stage: adult cats — complete dry food
  • Made in Europe
  • No artificial preservatives, taste enhancers or colours

Packaging transition: the zip closure has been removed and the bag design updated. Same recipe inside.

Frequently asked questions

Why do neutered cats gain weight?
Neutering lowers metabolic rate and typically reduces activity, while appetite often stays the same or increases. A lower-fat food closes that gap without leaving your cat hungry.

What does DL-methionine do?
It's an amino acid that lowers urinary pH. Struvite crystals form in alkaline urine, so a more acidic pH makes them less likely — relevant because neutered cats are somewhat more prone to urinary problems.

Is 11% fat too low?
Not for a neutered indoor cat. An active outdoor cat would do better on the standard Adult recipe at 20%.

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.

Made my cats ill

I did a previous review but it hasn’t been listed?? I have fed my cats purizon for 7 years and they have always loved it. I ordered the most recent pack, the double version as it’s always been good and better value. Firstly I noticed the zip close has gone. Secondly the food has changed. It’s not as moist as it was and a different size. \nI have had my cats sick more than usual and the only thing that has changed is this food. other reviews state the same. Have reported as Im concerned.

Deborah King
Not a good change

Ordered the double pack of this for my cats as they have loved this for years. It seems drier than before and the lack of the zip lock is a nightmare for keeping the food fresh. Now my cats won’t touch it and when I mix it with another flavour they are sick and have the worst smelling poo. I really don’t trust this anymore.

Recipe and packaging change

Have been buying this food for years, and my cats have always loved it. Since the summer, Purizon have permanently (I've been told) changed the recipe. It is now not as popular (whereas my cats used to fight over it!), the bag is no longer resealable, plus since the recipe change, my partner's cat has suffered with colitis, vomiting, had a vet visit, and is now on a hypoallergenic diet (which may or may not be a coincidence). I won't be buying this food for my cats again.

What’s changed??

My cats used to love this - they still do, but after feeding them from a new bag delivery yesterday one has diarrhoea and the other is scooting on her bum.\nI won’t be feeding them this again.

Change in Product Quality After Multiple Orders

Unfortunately, I experienced the same issue with my order from 13/06/2025 as other reviewers. This was my third time ordering this packaging, but this time the bag is not resealable, which is very strange and inconvenient given the size. What concerns me more, however, is the change in color and granule size. In addition, it cracks more easily and causes problems with the auto-feeder, where it often gets stuck. I’m now looking for a substitute.

Need a refund .Not acceptable as cats been on this original sterilised chicken and fish for years . Now losing weight . Not supposed to just change their diet suddenly but had no other food left .

Bag change disaster

This has been my cats go-to for years. Now the 6.5kg bag is not resealable, seriously??? I've never seen so much left behind. Very poor form.

Changed

Just wondering if anyone else out there has had a problem with the latest batch of Purizon sterilised chicken & fish. New packaging without resealable zip. Different colour, also cat put his nose up. Eventually got him to eat but now has diarrhoea. Got another bag sent to replace and exactly same batch and issues with cat.

My cat won’t eat this, would rather go hungry after tasting it only

My 9yr old sterilised cat Miya refuses to eat this no matter how trying to introduce it, even preferring to go without any food. My Dachshund Rolo eats anything apart from raspberries lol, when I gave him a biscuit of this food to try to encourage the cat he put it in his mouth three times and again spat it back out. Stunned me he wouldn’t eat it at all either, sadly this food is a fail in this house. Hopefully other cats eat it fine though! 1 star would be harsh so 2 instead

Issue with kibble

I’ve used this product before with no issues, but this bag had a mix of kibble of different sizes and when I queried with the manufacturer, it appears that it has been mixed with other kibble including kitten kibble - if you have this product and the size of kibble is not uniform, it may also be affected. I’m still waiting for the manufacturer to resolve this.

Very short expiry date

non kibble eater wolfs tis down

My cat normally won't eat dry cat food - there's always a bowl to supplement her wet food diet if she's hungry or I'm home late.\nI got these with PetsZo points thinking it was a treat food like dreamies - she absolutely adored it and ate a bowlful. Will definitely be buying her some more.

My cat loves Purizon

Sadie is a fickle Russian Blue princess but Purizon is one kibble she devours without complaint. So glad it's back at PetsZo after being unavailable for a while!
