Rose,

I've read that they are testing a GPS tracking device (for dogs?) in Europe right now. It's tied into cellphones so that you can dial a number and when you get close to the collar (and animal, with luck...) either the phone or the collar will ring. I remember when I read it that it seemed neat and that I wished it were being tested in California. Does anyone else remember this article? Was it posted here?

I need a memory transplant!

It seems like the device was relatively heavy (several ounces) which is why it's being tested on dogs, not cats. Maybe it can be scaled down/ refined soon. Does anyone else remember reading about this?
