Take this news story, for example. Willow the cat escaped from her Colorado home five years ago, and thanks to her microchip (and the fact that her owners kept the information up-to-date), she was recently discovered living in Manhattan (that's over 1,800 miles away!). She'll soon be returned to her excited -- and somewhat puzzled -- owners, who are thankful they decided to safeguard Willow with the chip. (The cat's owner even says she'd microchip her kids if she could.)
Find out more about pet microchips (we've blogged about HomeAgain microchips and if they're ISO compatible) and read the full story of Willow the wandering cat.
