Is microchipping safe for my cat, even if they are old or sore?

Updated on September 23rd, 2025

Are there any risks to microchipping cats? Should I wait to microchip my oldest cat - he just (recently) started medicine for arthritis so his body is already all sore and painful? Can microchips be inserted wrong? What happens if they do get inserted wrong or move inside the body after insertion?

Microchips are very safe. They are inserted under the loose skin above the shoulders with a large hypodermic needle. It's over and done very quickly, just a few seconds. Most cats grumble or hiss, but it is over with very fast. Most microchips implanted today do not migrate under the skin but remain where placed. Anyone administering a microchip is familiar with the method of inserting it properly.

    Microchips have very few risks. Occasionally they can cause a reaction or infection at the injection site. There are rare reports of microchips migrating into the chest or abdominal cavity or occasionally even the spine. There is brief pain associated with the chip placement due to the needle. All of these risks and complications are very rare, and most cats never have a problem with microchip placement - in my opinion the benefits far outweigh the risks.
