Dear Christopher Cat
Two of our cats try to run away whenever the door is open, so we are thinking about having them microchipped. Are microchips safe?
Yes. I am chipped, and I highly recommend the procedure.
Millions of cats – and millions more dogs and other animals – have been permanently identified with microchips over the past twenty years without ill effects.
Microchips are coated with a biologically inert material, so they pose no problem.
Moreover, no anesthesia is required, because the tiny, rice-sized chip is injected through a hypodermic needle, under the skin between the shoulder blades.
The chip has no internal power, but instead emits a signal when activated by a scanner. The scanner displays the chip’s unique number, which identifies the animal.
Escaping from the house without identification poses an enormous risk, however. Sometimes I sneak outside by darting between the dogs’ legs when Mom lets them out.
I feel secure knowing that if I ever need it, I’ve got permanent identification. That microchip is the cheapest insurance Mom ever bought.
An added benefit is that the microchip number can be used for a dog’s lifetime license in Pennsylvania.
