All of mine are microchipped. Since Katrina and the many, many lost pets left behind... I made up my mind that ALL of mine would be microchipped and they are.

Also, I will repete Klingers story.. Klinger (my neighbors cat) is an escape artist and will escape any/every chance he gets. He got out in 2005 and Mike was beside himself with worry. He saw a cat that looked like Klinger at a house close by and walked up in the yard and asked the lady if that was her cat.... she said it was... Turns out, the cat was Klinger and another neighbor of ours walked right up in that yard and grabbed him and brought him to me. If this should happen to your cat, microchipped, you could PROVE it is you baby!

Also, with as many natural disasters as there seems to be these days, being microchipped can PROVE that is your baby and hopefully help it find it's way back to you if you should be seperated.
