I use different colored paper and print out Name, DOB, color, and any health issues (i.e. adrenal, insulinoma). Each tag is only two by three inches so not terribly big, but can pack information on each tag. The tags are different colored to specify male/female. I purchased a low cost lamination machine at my craft store, (Before you laminate you can also hand write information that another person may need to know (i.e. not good with other ferrets, hand shy, etc) I laminate each whole sheet, cut the tags out, punch a hole in and hang on each tag with a plain metal shower hook. Hope this helps, melissa m. nelson, CPC The Full Nelson Ferretry The Ferretry in the Country [Posted in FML 7873]
