Description

A complete veterinary wet food for adult cats that need to lose weight. Low calorie content with high protein to preserve lean muscle and support a healthy weight loss rate.

Why your cat will benefit

  • Low calorie content for effective, controlled weight reduction.
  • High protein maintained to preserve lean muscle during weight loss.
  • Moderate fibre for a sense of fullness at lower calorie intake.
  • Chicken recipe for consistent palatability.

Features & specification

  • Dietetic complete wet food for overweight adult cats, in pouches.

Important — please read before ordering

  • Consult your vet before feeding a veterinary diet.
  • Safe weight loss in cats is slow — around 0.5–1% of body weight per week. Faster loss risks hepatic lipidosis. Your vet should set a target weight and timeline.
  • 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.

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.

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

Disgusting

I need to buy a diet food and knowing Parina I thought it should be OK but it’s absolutely revolting. I’ve put it out until three times now and my cats just look at it and walk away. I myself think it looks disgusting so I would not recommend it to anybody.

C
Claire
She seems to like it a lot!

I tried to start my cat with a small amount of this food accompanied by the other food she’d been having for a long time. However, she ate this and left most of the other food, so I’ve called it a win! She’s a fussy eater. I’ve had all sorts for her in the past and had to go back to her previous food. She’s still eating this with gusto! I guess it just depends on the cat and what they like or dislike.

Who Loves A Diet?

My cat tried to trip me down the stairs today. TWICE! I’m sure she was saying; “I HATE YOU!”, like my kids did when they were 13 & 14 (still do). I know I prefer a Krispy Kreme to an Apple & I guess Blue feels the same. But if I keep feeding her like I do, the vet says I will kill her & that means the kids will hate me as much as my wife! The food is obviously tasteless, so I started mixing it 50/50 with her old food & it’s working. Next week I’ll try 60/40 & so on. She is family & I need to try

Vet recommended this diet for health condition

Suggested as a treatment by vet for health condition. Seems to be doing its job for keeping health condition in check (not obesity). My cat will eat it, but prefers her sister's food!

Not recommended, it taste rally bad

My cat can eats everything and is not fussy at all. She is overweight so, I bought a lot of this food hoping to help with her weight management. If I put this food in her bowl she looks at me with such a sad face that it breaks my heart. So in order for her to eat it, I have to mix the product with other food.. which nullified the use of a weight management product as this. I have to manage her calorie’s intake manually and make sure she eats the correct amount. Don’t buy.

Timmy's Decision

Timmy will not eat this product. He looks at the plate and then at me...I'm not eating this. Nothing wrong with the product, just got a fussy cat. He does eat other Purina pro-plan meals, sterilised senior.

Change for weight loss

This product was recommended by our vet to help my cats loose some weight.\nAfter gently introducing the food to my cats, they seem to enjoy the food.

Clean bowl every time

My cat has been on a diet for a year now and has lost 3kg using the Royal Canin Satiety, however he’s been getting bored of the same food everyday so I decided to try this and so far a clean bowl everytime and a happy boy.

NEEDS MORE FLAVOUR

My big fat Grey Gorgeous Boy BENJI will literally eat anything. We call him the sweeper as he goes round all their bowls. You have to be fast to cat him. \nBut on a serious note I’m trying a variety of foods & it’s hard work\nThis one hes not fussed on so I mix with normal adult food. He leaves some but always go back\nTHESE SPECIAL DIET FOODS WE PAY GOOD MONEY FOR AND DONT YOU THINK OUR CATS DESERVE BETTER. MAKE IT APPEALING TO THEM AS ITS NEARLY MORE THAN DOUBLE NORMAL CAT FOOD PRICE 🙈🙈

Sarah
Massive to change of price overnight

I have buying this food for my cat for over 2 years as she is on a diet, they have changed the packaging and also the price so having to order from elsewhere now as its already really expensive for a 4% meat content food so wont be making use of my PetsZo membership discount.

S
Sharon
Fussy eaters

I have had the same problem with my cat, as in another review. My cat would only lap up the gravy and leave the meat; therefore not getting his medications correctly, so i added a different food (animonda integra) that he usually has. I mashed them both together and gradually weaned him off the animonda and now……as long as it’s all mashed, he will eat all of the purina obesity food.

Jon Henderson
recommended by vets

Have been ordering this as recommended by vets but unfortunately every time the cat loves the gravy it comes in but leaves all the meat without fail am at a total lost as to wether keep buying it as throwing so much away all the time so don't konw if it's worth the cost.
