Microchips are very small and implanted under the skin of the cat. The microchip has a unique identification number that can be registered online with owner information. If someone finds a cat, they can take the cat to be scanned to see if it has a microchip. This allows the finder to access the owners information and reunite the cat with its owner.
If you are unable to keep a cat that you have adopted from HKKR, you can contact us to return to the kitty to the rescue. We have a strict do not re-home policy in place. It does not matter how long ago the kitty was adopted, we will always take them back.
