Quick answer
To advertise kittens for sale in the UK, list them on a dedicated pet marketplace where buyers search by breed, price and location. On PetTrader you create the advert, pass a photo-ID check, and it goes live to UK buyers — one advert free for verified private sellers, and 12 months free for the first 200 businesses. Typical UK prices for kittens are £200–£1,500, so price yours in that range unless you can justify more.
| Where | Best for | Cost | Watch out for |
|---|---|---|---|
| PetTrader | Reaching UK buyers actively searching for kittens, with breed, price and location filters. | One free advert for identity-verified private sellers; 12 months free for the first 200 businesses and breeders. | Sellers are asked to complete an identity check, and checked accounts carry a Verified badge. |
| Breed clubs and registries | Pedigree animals with registration paperwork, sold to knowledgeable buyers. | Usually membership-based, sometimes free to list. | Much smaller audience, and most only accept registered stock. |
| Free classified sites | Cheap exposure when you have plenty of time to filter enquiries. | Free, with paid bumps. | Little or no seller checking, which means far more time-wasters, low offers and scam messages. |
| Word of mouth and waiting lists | Established breeders who already have repeat buyers. | Free. | No use at all if you are new, or if a home falls through at short notice. |
| Social media groups | Local reach and quick questions. | Free. | Most large platforms ban live-animal sales outright and remove the posts, and there is no buyer protection. |
Anyone selling kittens as a business — including breeding and selling three or more litters of dogs in a 12-month period — needs a licence from their local council under the Animal Welfare (Licensing of Activities Involving Animals) Regulations 2018. The licence number has to appear in the advert itself, and PetTrader has a dedicated field for it.
Kittens must stay with their mother until at least eight weeks — most breeders rehome at 12-13 weeks after vaccinations. Buyers must see the kitten with its mother under Lucy's Law, which covers cats as well as dogs.
All cats in England must be microchipped by 20 weeks old and registered to the keeper. Say in the advert whether the kitten is chipped, vaccinated, flea and worm treated, and whether it is registered with GCCF or TICA if pedigree.
Stock images and photos lifted from elsewhere online are the number one sign of a scam advert. Pictures must be of the actual animal you are selling, taken where it currently lives. Adverts using images found elsewhere are removed.
Age, sex, health treatments, any known conditions and how the animal has been kept all belong in the advert. Under the Consumer Rights Act a buyer can come back to you if the animal was misdescribed, so being straight up front protects you as well as them.
PetTrader will not publish a pet advert until the seller has passed an identity check — photo ID matched against a live selfie. It takes a couple of minutes and it is the main reason buyers trust adverts here over free classified sites.
Full detail is in our safe selling guide and how PetTrader works.
Identity-verified private sellers get their first advert free. The first 200 businesses and breeders to join get 12 months of their subscription free, which includes directory listing, unlimited adverts within their plan, one free news post, one free event and one free job vacancy each year. After the launch offer, single adverts are charged per pet type and subscriptions are billed monthly or annually.
The best place is a dedicated pet marketplace where buyers are already searching by breed, price and location, and where sellers are identity-checked. On PetTrader every kitten advert comes from a verified seller, which cuts out the time-wasting and scam enquiries you get on general classified sites.
Yes. Identity-verified private sellers currently get one free advert on PetTrader, and the first 200 businesses and breeders get their first 12 months free. After that, adverts are paid so the site stays free of scam listings.
It is legal, provided you follow UK law. Selling animals as a business needs a local council licence under the Animal Welfare (Licensing of Activities Involving Animals) Regulations 2018, and the licence number must appear in the advert. Kittens cannot be sold under eight weeks, must be seen with their mother, and all cats in England must be microchipped by 20 weeks old.
Minutes. Create the advert, add your photos and details, and complete the identity check. A strong automatic ID match publishes the advert straight away; our team then reviews it for the verified badge.
Clear daylight photographs of the actual animal, an honest description, a realistic price, and full details — microchip, vaccinations, worming and pedigree registration. Adverts missing these get far fewer serious enquiries. See the live adverts at /pets-for-sale/kittens for examples of what good looks like.
