Thank you for the information Lisa. Dennis and I have also been discussing the options for our kitties..... what to do to get the cats out, if we must move quickly due to fire...flood..... where to meet, and the possibility of having everyone microchipped. I will read up on the types of microchips too. We have pet stickers on our door windows and a prearranged meeting place- but that is all we have done.Thanks so much!
