Description
FELIWAY Optimum is the most advanced FELIWAY solution that has been proven to help with the common signs of stress BETTER than ever before! Not only does it help with the common signs of stress, it also helps multi-cat households get along. It contains a NEW feline pheromone complex, with the help of new bioengineering technologies, the FELIWAY team discovered a new pheromone complex. The discovery of this complex brings enhanced serenity for cats.
Cats are sensitive creatures and can be unsettled by different events such as new furniture, redecoration, moving house, the arrival of a new baby and more. They will show their signs of stress in different ways – hiding can be a common one, urine marking, scratching or fighting with another cat in the same household. Clinically proven, FELIWAY® Optimum reduces the appearance of common signs of stress, whilst delivering enhanced serenity. It will help reduce scratching, urine spraying, tension and conflict between your cats, hiding and reaction to change. Changes observed were a reduction to scratching by 73%, Urine Spraying 77%, Tension and Conflict 72% and Changes and Fears 73% (**De Jaeger, X., Meppiel, L., Endersby, S. and Sparkes, A. (2021) An Initial Open-Label Study of a Novel Pheromone Complex for Use in Cats. Open Journal of Veterinary Medicine, 11, 105-116. doi: 10.4236/ojvm.2020.113006.)
Easy to use, just plug the diffuser in and leave it on at all times for the best results – just plug it in where your cat spends most of their time. A monthly refill is necessary to ensure continued serenity.
The Feliway® Optimum diffuser simply plugs into a socket and releases an innovative mix of pheromones into the air, helping to provide harmony and an increased sense of security for your cats. The Feliway® Optimum is only perceptible to cats, so it is odorless to humans and any other animals in the house will not be affected. This product is recommended by veterinarians to help counteract stress‑related behaviours such as urine marking, hiding, excessive scratching and over-grooming. Feliway® Optimum can also help reduce tension and conflict between cats, ideal if you are adding a new cat to the family. Many veterinary practices also use this product to help make the whole experience more pleasant for your cat.

Ingredients:
Analogue cat pheromone complex [FPhC] (2%), isoparaffinic hydrocarbon q.s. (48ml)
Usage instructions:
Simply plug the diffuser into a socket in the room where your cat spends the most time. For maximum effect, leave the diffuser plugged in continuously and replace the bottle approximately every 30 days. Use the bottle label sticker as a reminder. A 48ml vial should last for around 30 days in a living space of 70m².
Only for electrical voltages of 220V. Use in a functioning socket. Do not connect to an extension cord, multiple socket, power strip, adapter or voltage converter.
The diffuser heats the liquid in the vial in order to release the Feliway® Optimum pheromone composition. This means the diffuser head may feel warm to the touch. Do not place it underneath furniture and ensure there is more than 1.2m of free space above the socket.
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.
