Here is a sad story, how 1 of my cats died. It was around 2-3 years ago this. Basically, the cat was very poorly. So me and my mother were going out for the day, and we decided to drop in at Sainsbury's to buy her favourite milk. We bought it and then came home.. My mother then said Blanch. In a quite high voice (Blanch being the name of the cat) and she kept saying it and then she saw her in a little corner..
Dead 
She also said to me, when we went out and shut the kitchen door, she looked at me like when she was a little kitten.. Makes the story so much sadder really. I still look back on it and it's quite sad.
