Because you don't know how long you will be blessed with them. Our next to oldest baby passed over the rainbow bridge today at around 4:20PM. She came in from her potty break and lay down and wouldn't respond when my wife called her name. She woke me up and as took Jazzabell from her arms I could tell she was passing out of this life. I got to say goodbye to her and hopefully our holding her eased her transition. Jazzabell - your'e gone, but we will meet again when we leave this plane of existence and we can romp in the fields to your hearts content with all our other fur babies that have gone before and after you. And yes, I'm heartbroken even though we have several other babies... this one was very special to me as it was a birthday present and she normally slept adjacent to me at night after giving me a "good night" lick on the cheek.
