Microchip Identification

A microchip is essential in locating your feline friend should they ever stray too far from home and is legally required for all cats in Hawaii.

What is a Microchip?

A microchip is an electronic device the size of a grain of rice that encodes a unique identification number for your cat. It is typically implanted between the shoulder blades using a specialized needle. Once implanted the microchip stays in your cat for life, providing a form a permanent identification that is often life-saving for lost pets. Implanting a microchip takes less than one minute, is inexpensive, and hurts about as much as a blood draw.


Effective July 1, 2020 microchip identification is mandatory for ALL cats and dogs over the age of four months on the island of Oahu.

  • Is your cat already microchipped? Good job!
  • Is your cat’s microchip registered?

If your cat was microchipped on Oahu in the past 20 years, their microchip was probably registered with the Hawaiian Humane Society’s microchip database. Unfortunately, as of July 1, 2020, the Hawaiian Humane Society is no longer managing a microchip database. What does this mean for you and your cat?

It means that you need to register your cat’s microchip with a national microchip database. You can register with the microchip manufacturer or a free online database. We recommend FoundAnimals.org – it is free and easy.

A microchip only contains a unique number – it does not store any of your personal or contact information.
Your cat’s microchip is useless unless it’s registered, and your contact information is current.

If we don’t have a microchip number on file for your cat, please call us to schedule a time to bring your cat in so we can scan their microchip. This is a free service.

If you do not have internet access or need assistance registering your cat’s microchip, we are more than happy to help!
