Hi Sara --

Let's see. Livvy was born 4-11-99 and was chipped early July 2001... She was about 27 months then and roughly 14 pounds -- she's a Maine Coon mix. They needed to clip a lock of her hair and she was a little stiff for not quite 24 hours. She seemed upset when we got to the vet, but hugely relieved when we got home. That seems to be a pretty common reaction to vet visits and not related to pain, just the smells and 'difference' of location?

I look on the pain of her getting the chip as a very low cost in the peace of mind it gives me and rather like the pain of her getting annual shots. There is some pain, but much less pain than getting an illness or getting lost would be for both of us...
