I think putting a microchip in our pets is a good thing.....my cat has one. He has had a chip in him for 11 years. The humane shelter from which I got him from puts chips in all the animals they have at their shelter. If an animal gets lost, it helps them find the owner. My vet scanned my kitty to show me the information on chip. It's pretty cool. He said it does don't hurt the animal, nor does the animal feel the chip.
