Oh such sad stories, I can understand the pain of losing pets.
About a month ago, I came home to find one of my rats clinging to the cage with a pointy spine and a very fearful look in her face. I had had my rats around 3 years at this point, so I knew her time was soon to come, but I quickly picked her up out of the cage with such a struggle and realised she was no more than skin and bone, this was a surprise to me as I feed them a good and frequent diet. I sat in my school clothes nursing her on my chest for about 9 hours, crying and telling her how much I loved her and was so grateful that she was such a loving and playful pet and friend. That whole night was like a bitter-sweet nightmare having to look into her deep eyes full of confusion, fear and fatigue. It had been hours nursing her, and she was still struggling to stay alive, I knew it was any minute that she would give in but she didn't, it was well past my bedtime and she was still alive, and I knew that if I put her to bed she would pass-away from being too cold. I had to make the heart-breaking decision to put her to bed, so I wrapped her up in three layers of warm cloth and gave her a nice big kiss. When I got up that next morning she was gone.
I'll never forget that look in her eye, so vulnerable and confused... but clearly grateful that I was there with her. It was that experience that made me vegetarian, to think of the billions of animals who die every year with that same look in that eye, I've never been able to look at a cow happily grazing in a paddock without thinking of that very look that Yeesha had in her eye, and that that cow would one day, too, experience the same thing.
Sorry, I know that's a long and sad story, but for me it's a valuable experience as it was the final realisation of the silent yet emotional value that every animals has.
