What Is a Microchip?
A pet microchip is a tiny electronic chip — about the size of a grain of rice — implanted under your cat's skin, typically between the shoulder blades. It contains a unique identification number that can be read by a scanner at any veterinary clinic or animal shelter.
How It Works
When a lost cat is brought to a vet or shelter, the first thing staff do is scan for a microchip. The scanner displays the chip number, which is then looked up in a registry database to find the owner's contact information. The entire process takes under a minute.
Importantly, microchips do not have GPS. They cannot track your cat's location. They are identification tools, not tracking devices.
The Implantation Process
Implantation is quick and relatively painless — similar to a routine vaccination. Your vet injects the chip under the skin using a sterile applicator. No anaesthesia is required, and most cats barely react. The procedure costs between $30–$60 at most clinics.
Why Registration Is Critical
A microchip is only useful if it is registered with up-to-date contact information. An unregistered chip, or one with outdated phone numbers, is essentially useless. When you move or change phone numbers, update your registration immediately — most registries allow online updates for free.
Common registries include:
- HomeAgain
- PetLink
- AKC Reunite
- 24PetWatch
Microchip vs. Collar
Both have advantages. A collar with a tag provides immediate visible identification — anyone who finds your cat can call you without needing a scanner. However, collars can break, fall off, or be removed. A microchip is permanent and cannot be lost. The best protection uses both.
International Travel
If you plan to travel internationally with your cat, many countries require microchipping as a condition of entry. Check your destination country's requirements well in advance, as some require specific chip types (ISO 11784/11785 compliant).
