Selling a Pet Online: What Responsible Breeders Need to Know

When to advertise your litter

It depends on you and demand for your puppies or kittens:

• Some breeders announce a litter is due before birth.
• Others advertise once they’re born; many wait until around 2 weeks old when things are calmer.

Whatever you choose, puppies or kittens must stay with you until they’re at least 8 weeks old.

Do I need a breeder’s licence?

You generally need a licence if you breed three or more litters per year, or advertise as a business. If you intend to breed more often, contact your local council about licensing for dog and cat breeders.

How much should I charge?

Price is your decision, but consider:

• Parents’ health testing and achievements (sports/activities).
• Your costs to raise the litter (including health tests).
• Current demand for the breed/type.

Your priority should be finding good homes, not maximising profit.

Finding buyers

To attract responsible buyers, try:

• Friends & family: They may be a great fit. Still check suitability.
• Referrals: Ask contacts if they know someone suitable.
• Reputable listing: Create a detailed, honest advert with clear photos and vet/health info.

Questions to ask potential puppy or kitten buyers

Use first contact (phone, email, messages) to assess fit. Ask:

Speak directly when possible, then give buyers space to think before deciding.

Meet buyers safely

• Ask for a photo ID (e.g., driving licence or passport).
• Have another adult present when possible.
• Trust your instincts—if something feels off, pause the sale.

Let buyers meet mum

Let buyers see mum with the litter to reassure them pups/kittens are well cared for and have not been separated too early. Seeing mum’s temperament helps them understand likely behaviour of the pup/kitten as an adult.

Show where the litter is kept, where they sleep, and allow buyers to see the whole litter for socialisation and fit.

Should I ask for a deposit?

Many breeders take a deposit to reserve a specific pup/kitten. A typical range is 10%–25%.

• Don’t set a deposit so high that it scares off genuine buyers.
• Always provide a receipt and write any conditions clearly.
• Be aware of fraud concerns; communicate openly and professionally.

When should I sell my puppies or kittens?

In the UK, puppies or kittens should not be rehomed before they are at least 8 weeks old. Early separation can negatively affect behaviour.

Before you sell: prepare your litter
