JS I've been reading this thread the last day or so but have waited to post, not sure if I was going to then, but to let you know that, like the others, its just something you do.. live with it I guess.
My sister has a bridge baby. Our Puddles (just a nick name for her) was a Lexy look-a-like. She passed on in January 2005 aged nearly 11. It was unexpected, her death, she was terminaly ill but not diagnosed until too late.
Puddly was such a character. She was, to me, as much my baby as my sisters. Even though she lived with my sister, I had known her since she was a wee kitten and she was very much a part of my life, pretty much every day she was somewhere near me. She was the most amazing character, and loved me nearly as much as she did her mummy, she loved that I used to spoil her rotten (or that she could get away with murder with me and knew it!).
Two years and bit later and I still cry when I talk of her, like now, but the memories of her, each day, are wonderful, almost bittersweet.
It does get easier to bear over time, the hurt is less each day but its still there. I miss her terribly some days, I miss her cuddles and the way she would remember if you spoke sharply to her if she climbed on the table when we were eating, she would wait about an hour then walk past you and swipe your ankle as if to say "shout at me will you!"
It is no wonder that when Lexy took one look at me with her little face so very much like Puddles that I fell in love with her. Its almost like Puddles said it was ok to bring a new baby into our family and it was an added benefit she was a B&W like our Puddly!
