Requiem to a small yellow cat

The small yellow cat adopted by my daughter a year ago passed away today. Eight days ago we realized he is sick and took him to the veterinary clinic, where they diagnosed that he was attacked by a violent virus, which his immune system could not handle. We were told that he'll probably last for 2 months or so, but it seems that this has been over-estimate. He had short life, only a little more than a year, but had a good life relative to his peers that live in the street. I have never been a cat fan, but over the last year he became part of the family, and was very attached to Hadas, my third daughter, he was very sad every time she has been away from home for a few days. For some strange reason the battery in my watch went dead at the same time he died, and my watch stopped. I have already replaced the battery, replacing a living creature will be more difficult, but we might adopt a new kitten after my daughter will get over...
