This story started... Well in early Dec 2007.
One of our three cats (Blue) had reached the old age of 13 years (plus a little bit. Her health was slowly declining and by the first week of December of 2007 she was near death. Now for some background on our cats...
Blue and Stormy had been born to a pair of alley cats that had mated in our yard, had kittens in the yard next door to ours and then began to be feed / received first series of shots from the lady whom lived two doors down from us. They were never apart in life and ended up being very good nanny / watch cats. They would take turns on watch during the night and if you stayed up you could watch the 'changing of the guard' and 'checking of all the beds'...and if a child was having a sleep over somewhere they would 'ask' (meow) at that child's door until it was explained to them what was going on. 4 years later we add a third cat (Spot...short for Spots Domino because she is a black cat with two white spots on her belly). Blue sees to her training and she joins the 'patrol'.
Now as I was saying... After my retirement (Nov 30th 2006) from the Navy we moved to Austin, TX and settled in. Blues health began to decline and by the First week in Dec 2007 she was being hand fed liquid / super soft foods. She still would use the litter box and tended to her watch post at the front door. I would get up in the mornings to get the kids ready for school and check on her, she would meow at me and sleep knowing that she had been relieved by me.
One morning I went to check on her, as I reached for her she gave a very loud, strong 'Meow!' and I said to her, "Well your feeling goo..." as I touched her I realized that she had passed during the night for she was cold and stiff to the touch. I am confident that she 'remained on watch' until I relieved her and that she said good bye to me.
Flash forward to the evening of 19 Nov 10, Stormy, Blues sister (Now 16 years 1.5 months old,) is showing Grey hair and is moving slowly and stiffly around the house. I'm in my bedroom and I hear from the hallway and loud 'MEOW', this did not sound like either Stormy or Spot, but like Blue (Stormy's sister that had passed nearly 3 years before)...I then heard Stormy meow as if in answer to her sister, then she meowed 3 more times, one sounded like she faced my closed bedroom door, and then one for each for the other two bedrooms... I call out to our oldest child and he tells me that Stormy is just acting weird in the hallway. He tells me later that Stormy exited the hallway and climbed into our pet travel carrier as if she expected to go on a trip... An hour later she was...gone... I 'know' her sister came for her and that she made one final 'patrol' and that they have moved on to a better place, together as they always had been in life.
