Benefits of Early Microchipping for Pets
A chip only brings a lost pet home if the details on it are yours. Until the record moves from breeder to new keeper, a scan leads to the wrong door.
If you’re collecting a new puppy or kitten in the next few weeks, there’s a good chance the chip is already in. That takes the hardest part off your list and leaves you one job that still really matters: making the record yours.
Why chip a litter before it leaves
In England, a puppy or kitten can’t be passed to a new owner unless it has already been microchipped, with the only exception a vet’s exemption certificate. For a puppy still with its mother, the breeder is responsible for the chip and the first registration. Our page on whether puppies must be microchipped before sale covers the rule in detail.
Cats Protection’s 2025 figures show adopted cats are more often chipped than bought ones: 89% of adopted cats are microchipped, compared with 71% of bought cats. That gap matters if you’re buying, because it means the chipping question is worth raising before you collect. Most responsible cat breeders chip kittens before they leave for new homes, at around eight weeks. If a vet decides a puppy or kitten should wait until it’s older and bigger, the breeder must give you a vet-signed certificate instead.
Why chip a puppy or kitten young
The timing matters more for cats. A cat is best chipped before it first goes outside, and if you adopt rather than buy, that will usually be the case already. For a puppy, check it’s microchipped before you take it home.
Kittens can be chipped, vaccinated and neutered at a single vet appointment, so one visit covers the lot. Our guide to what to expect at the microchipping appointment explains how that appointment works.
A record that starts with the breeder
A new pet’s chip is usually registered to the breeder first, and the record stays in the breeder’s name until you move it to yourself. The chip itself holds only a number: the owner’s name, phone number and address sit against that number on a database, and that record is what matches a scan back to the owner.
Battersea Dogs and Cats Home’s research traced 83% of inaccurate records on stray dogs to new owners who never updated or registered. If your pet strays in those early weeks, a scan leads to the breeder, not to you. Rescues rely on an up-to-date record too — stale details leave staff unable to tell an owner their pet has been found.
What it means for the new owner
In England, when a cat or dog changes hands, the new owner must put their full name, address and phone number on the database, unless the previous owner already has. You can register the microchip in your name as soon as you get home, and it’s worth asking your vet to scan the chip at the first check-up so you know it’s readable.
Checking the record isn’t a one-off job. Pet Database’s own research found owners last checked their microchip details an average of 15 weeks ago, with almost a third never checking at all. A quick check after a house move or a new phone number keeps the record useful. If your new pet isn’t chipped yet, our guide to the best age to microchip a puppy or kittenexplains when to book.
Breeders handle the chipping; the record is your part, so register it in your name with Pet Database once your new pet is home.
