We can't wait to get some fresh air and its so easy to become distracted, wander further from home than we should, and before you know it we are lost! Do not believe everything you read "Tom Cat Walks 2,000 miles from New Jersey to Texas". Trust me, he did not walk...he had a tag and a truck driver found him and dumped him at the nearest shelter.
This is why I am a strong advocate of Operation ID. You must always have an ID around your neck so if you should lose track of time and wander off, someone will help you get back home.
I like Doctors Foster Smith catalog for purchasing. Right now they are giving a 15% discount on name tags in Solid Brass, Stainless Steel, and Aluminum. This can save your life. Over 8 million furry felines and canines are taken to shelters each year because of no ID. Please, get your ID today. My favorite magazine "Cat Fancy" also has an article all about this.
