what a lucky kitty you are that your family took you in so that you could live a very long life. a shelter is not always the best place to be especially if they find a problem with the animal such as too young or too old or too many. i praise GOD that you survived and lived a long life of 21 years.. more glory to you as cotd.. may you enjoy your day and everyday to the fullest that you possible can. happy birthday 21 years to you.. if you are human you would be 100 years old. 20120507.0328
