A little public service announcement: If your pet has a micro chip remember to register it! I just signed up Tibby and Dhali on the Microchip Registry - It's free and it's for all brands of micro chip. It's just a non profit registry to help pets get home when they are lost.
One of the things that I worry about with my pups microchip: There are so many brands of micro chip. Dhali and Tibby even have different brands, because Dhali was chipped before he came home with me - so how will a rescue/vet/ect. figure out which company to look at to find me?
I think this registry is a good idea. Simplifies things!
