That is really sad - I am so sorry to hear it. I know for me, I get really attached to my pets and losing them is the hardest thing in the world. I have always had dogs and cats both through my life but have been more of a cat person lately. I lost my 12 year old cat in 2000 and it was 8 years before I got another one. I still miss that guy but I love my new cat too and am glad I have her.
