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.

3. Delivery times

Time in transit after dispatch depends on the delivery method selected at checkout and your location. Total time to receive your order is therefore the dispatch window above plus the carrier's transit time.

A small number of products are shipped from outside the UK and take longer to arrive. Where this applies, it is stated clearly on the individual product page.

4. Delivery area

We currently deliver within the United Kingdom only. We do not offer international shipping at present.

Please note that a small number of bulky items cannot be delivered to Northern Ireland. Where this restriction applies, it is noted on the product page.

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.

6. Delays

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.

8. Contact us

For any questions about shipping or the status of an order:

Phone: +44 7782 276061

Very interesting.. . .

I like this food very much. 3 cats 3 British shorthair indoors, two one year olds, one 2 and half year old almost 3. One was on royal canin gastro now he is on this one and loves it no problem (sensitive stomach), the other two are putting on weight so was told by vet to get something for indoor cat. I tried many but I have to say, 3 different cats of BSH personality and stomach differences - they ALL love this. I will stick to this food for 3 of them!

Cats eat it all up

Have been feeding my two cats this for about 14 years. Both eat it with relish and it is a very economical food with good quality ingredients. One of my cats used to get an upset stomach until I tried them on Hills. No problems since then. Would definitely recommend.

Happy cats!

We bought this because our cats were becoming less mobile as they age and so they were putting on weight. This solved the problem and they had no problems switching to this from the regular Hill's food.

Quality food, low price

This is a very good quality food, keeping the cats very healthy. One of my cats has a very sensitive stomach and she seems to do very well on this diet, so I'd recommend giving it a try if your cat is a bit delicate. They all dive into their biscuits morning and evening, so clearly no problems with palatability! It's helped maintain my two overweight cats weights, but not lose weight. Doesn't seem to harm my 2 who are an ideal weight. And of course, best price available!

best price available

I've shopped a lot online for this cat food, and you have the best price available. The food was recommended by my vet because both my cats are a bit overweight. I can't say they have lost any weight as a result - both cats go outside and who knows where else they dine!

Balanced Healthy Food

My cat Sooty has digestive problems. He cannot process food properly and therefore he puts a lot of weight on, even if he goes outside in the countryside and gets plenty of exercise. (pathology confirmed by the vet). This food is brilliant to keep Sooty's weight under control. It is complete and balanced and slightly lighter than normal food. The pellets are just the right size for a cat mouth. This food does not cause bad breath (much apreciated!)My other cat, Petal, which has not digestive problems, eats the same food and she is perfectly fine. Sooty's daily amount of food is weighed, while Petal can eat as much as she wants. I order the bags of 10 kg by two then I don't have to worry for more than a month! The bags are resealable so I don't have to transfer the food in a container to keep it fresh :o)

Weight Problem

I have 4 cats and I've always used Hills but 2 of my cats have weight problems and I've even tried a Hills reducing diet for them prescribed by the vet which hasn't helped. I always weigh the food and I have 2 cats who have no weight problems at all. I think am going to have to try a grain free diet as I've heard this can be better for weight problems.

Good quality food

Our three cats have been on this hills light food for years after the vets told us they were getting a bit tubby. Cannot fault it. It has always annoyed me that we were getting through a 1.5kg bag a week but the economy pack of 2 x 10kg bags I ordered works out much cheaper. My wife doesnt worry about money when it comes to her moggies but I certainly do!! Will definitely be repeat ordering!

Always popular

Our six cats have been on Science Plan Light Chicken for over ten years. All of them love it, and keep healthy and the correct weight. We use a graduated scoop and individual bowls to make sure they each get the correct amount each meal. The bags have a best-before date about a year ahead, so stock up when there is a good offer.

Cracking value

Our vet recommended this diet for our cat and we were flabbergasted by the price. I tried buying it direct from Hills. Then I had a brain storm - Google! The cat food is excellent. We have two Bengals and they are fussy eaters. Our male cat was 10KG and this stuff really works. He is now down to 7.7KG. He has a nice glossy coat and looks healthy. Great stuff.

Hills Science Adult light chicken

I have two cats one "Spicey" is normal size but her sister "Sugar" has always been on the plump size she is known as "the little fat thing". By using hills adult light it has managed to keep her weight even and she is a very healthy 3 year old and Spicey loves the food too.
