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.

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.

My cat loves it

My cat thinks it’s a treat and demands it. She gets offended when she gets served different food. Wakes me up at 6 am wanting to eat it. Yes it smells bad for humans but it’s fish so yeah, it’s meant to.

Even the greedy visitors won't touch this

My girls sniffed it and chose hunger over trying it. Tried to give it to the greedy visitors that come daily, this is the first thing I've ever seen them refuse. One even chose the cheese and coleslaw sarnies I threw out to birds than give this a lick.

Charlotte
Cat loves it

Don't listen to the negative reviews. Yes it stinks but it's supposed too. It's got mackrel and sardines so you should expect smelly lol. My cat loves all fish types besides prawn so he loves this! If your cat is more or a tuna or salmon eater then they may not like other fish but you don't know until you try.

My cat gobbles it up

My cat is fed Thrive wet/dry combination daily and this is one of the wet flavours she absolutely loves! Yes it's stinky, but there's a variety of good quality fish. My cats clears her plate. Maybe we are lucky but have never experienced a bad batch so will continue to buy

Cats enjoy it

Yes this is a pungent cat food, but I like that you can see the various real fish pieces inside it, and that its a complete food. My two boys never leave any in their bowls so they like it. I've been ordering it for two years now.

M
Maria
Great for cat

I feel like the bad reviews don't do this justice, maybe it was indeed a bad batch? Now, this one does smell stronger than their other flavours, but as far as I know that's just how mackerel always smells! It's a pretty strong fishy smell. Our cat, however, has no problem and always gobbles it up. The vet was very happy to hear that he likes fish as it provides lots of nutrients for cats! Our cat recently got "tired" of the tuna flavour so this is a reliable alternative,

High quality food despite how it looks to humans

Our cat finds it a great food despite how it looks to us. Great to have such a variety of different ingredients to usual. Mackerel, whitebait and shrimp in mackerel stock so a very wet food that is a complete food and meal. Don't be put off by the look as the cat wont..

Great for my 14 yrs cat

Not sure why some people think the smell is quite unpleasant, perhaps just a bad batch? My cat loves all the fish flavours of thrive and it smells nothing but fish, which is what it should smell like. I’ve bought quite a few of the 24 packs with no issues at all.

fussy cats love this

at last a complete cat food that my cats will eat that is real fish. I've bought a few times this year also the chicken one & had no issues, smells nice & fresh & ordering more today :)

My fussy cat loves all the Thrive range including the Ocean Fish

It contains ocean fish and the clue is in the title, it contains oily fish plus crustaceans as I've found shrimp in it plus what looks like squid and my girl loves it. Yes it is definitely fishy smelling but not Rancid so maybe some customers have had a highly unusual bad batch but we've had this a number of times now and it is no more offensive than anything fishy. I keep trying other products but my girl turns her nose up at anything that isn't Thrive.

M
Monika
Never again

I normally dont write reviews but with this one I had to. Its terrible. Smells disgusting. My 2 cats just smell it and walk away not even touch it. Other tastes of this brand is lovely but this ocean one I would avoid.

E
Emily
Appalling!

I would give this minus stars if possible! Like other reviewers - I could not believe how fowl the smell was when I opened the can. Surely this has got to be a bad batch that should be returned to the manufacturer? The open tin went straight down the waste disposal with a gallon of water and disinfectant and Ive kept the others as potential return as you have to witness the stench it to believe it!! So much for trying a different flavour for our now 'highly offended' cat!!

M
MH
RANCID!

I was hoping that recent bad reviews were just isolated incidents, but when I opened this food I knew something was off. It smells like actually rotting garbage, and my cats of course wouldn't eat it. Extremely disappointed as I feel other thrive wet food are very good and It's what I normally give my cats, so to have such a disgusting product being sold with a straight face is vile.

My cat hates Tuna and Salmon

My cat loves this variety and the Sardine and Mackerel. This is the first cat I have been owned by who hates Tuna and Salmon in any form.

Disappointing

My cats love the tuna, and tuna & salmon so I thought I'd try the Ocean Fish - there was more gravy than fish to start, and neither one of them had more than one taste! Walked away a few times, compared to the other flavours which they devour! Maybe if there was actual fish flakes? It was very soupy.

C
Charlie
A dining disaster

My cats love the tuna, tuna/salmon so I'd thought I'd try to Ocean fish too. They did not like at all!! A sniff at best, I even tried to add real tuna to it to entice them but they were not interested. Waste of money sadly. \nAlso, it is mostly gravy and very little fish - usually they love gravy but not this one. Very disappointed.

J
James
very smelly

This smells disgusting. The awful fishy smell permeated the whole house! My cat wouldn't touch it either. The Tuna and Salmon is a lot better and my geriatric cat loves that one.

Looks like a waste product

I love other Thrive products, but this looks and smells just awful, and none of my cats would even look at it let alone eat it. I ended up having to discard it. The content looks like thin fish soup with indeterminable, unsubstantial pieces of fish.

Great replacement for non-complete foods like Encore

Our cats love Encore as a treat, but now I've found Thrive Complete I can give them this instead - and I think it's slightly cheaper than what we were paying for Encore. \nHonestly, Ocean Fish variety looks very unappetising, but the cats aren't fussed about what it looks like, and the empty bowls suggest it tastes better than it looks.
