I just got my cat Sophie microchipped. It was a small fee at the vets, and like a $10 fee to the microchipping company (Home Again). It's so small, I can't even figure out/feel where they put it!

I think there are different types of readers, but I think the companies generally loan the scanners to the shelters for free, isn't that right? I figured I might as well go ahead and do it anyway, it can't hurt, right?
