In case your kitten ever strays, she should always have proper identification.
Make sure an ID tag is secured on the collar. It should list her name as well as your name, address, and phone number.
Microchips and tattoos have become increasingly popular. Microchips, inserted by veterinarians without surgery, are tiny capsules that contain a unique registration number. This number is entered into a database that can be scanned at pet shelters, veterinarian clinics, or humane societies around the world. The chip will link your kitten to you no matter where she is.
If you travel with your kitten or have recently moved, a microchip or tattoo can be a smart extra precaution in case her collar gets lost. Regardless of what method you use, make sure the contact information associated with your kitten is always current.
