The microchip, which is approximately the size of a grain of rice, is injected beneath the skin with a needle, similar to a vaccination. There is no anesthesia required and even the smallest animals such as fish, puppies, and kittens can be safely microchipped.
Each microchip has a unique code number. When a special, hand-held scanner is passed over the area where the microchip has been implanted, the scanner “reads” the microchip and displays its code number. Code numbers are stored in a national database where the owner’s contact information is maintained. The animal care agency can then retrieve the owner information from the database and contact the owner so they can promptly recover their pet.
