Most microchip implants consist of three elements: an integrated circuit commonly called a “chip” a coil inductor, sometimes with a ferrite core and a capacitor. The chip holds exclusive identification data and electronic circuits to code that information. The coil acts as the secondary winding of a transformer, taking in power inductively joined to it from the scanner. The coil and capacitor together structure a resonant LC circuit which is tuned into the frequency of the scanner's oscillating magnetic field to manufacture power for the chip. Then the chip transmits its data through the coil back to the scanner.

A microchip implant is a passive RFID device, without an internal power source, it remains lifeless until it is powered by the scanner. These mechanisms are encased in biocompatible borosilicate glass or soda lime and hermetically sealed. Except for uncommon complications, cats are unaffected by them.

In felines, chips are typically inserted underneath the skin at the back of the neck amid the shoulder blades on the dorsal midline. Thin layers of connective tissue structure in the region of the implant and hold it in place.

Most shelters rely on this system. Many cats have been returned to their homes thanks to this wonderful creation. It is strongly advised to have your feline microchipped, even if he/she is a strictly-indoors feline. Once in a while, these felines sneak outside, fear the strange sights and noises and run off to worlds unknown, unable to find their way back.
