What is microchip? Why it is important?

Updated: Mar 7, 2025

A microchip is a tiny, computerized chip that's placed underneath your cat's skin, usually around the shoulder area. And the purpose of it is to be a form of identification should your cat get lost and wind up at the shelter or a veterinary hospital.
We do microchip our kittens because if they were ever to get lost for whatever reason, the microchip is used to identify who the cat is and who the owner is, and get them back to you as soon as possible.
Another important reason to microchip your cat is for international travel. If you plan to travel or move to a different country with your cat, it is important to check the requirements. Your veterinarian will have to complete export paperwork and many countries require pets to be microchipped or they will not be allowed in. Rabies vaccination is also required for travel, and if the rabies certificate does not contain the microchip number, it may not be considered valid.
Additionally, having a microchip allows for the option of electronic pet doors with microchip sensors. These doors can be installed to let pets in and out, as well as into specific feeding areas – an option that is particularly helpful if you have multiple cats that need different diets.
We recommend registering you cat with PetLink immediately after arriving home. However, with more than 30 registries in the United States, how do you know which one to choose?
