Input: Text: this happened to me years ago but i have always felt guilty about what happened. i moved to singapore and lived in an apartment with my wife and daughter. we lived on the 10th floor and our neighbour who owned a cat lived on the 11th storey. this cat that we are talking about spends most of its time resting on the window grail, observing whatever that's happening. 

one day my daughter told me that her teacher wanted her to find something on the net and share it with her classmates. my daughter was very excited and decided to do a write up on fish and its skeleton. also, she wanted to have an actual fish skeleton as visual aid. naturally i have to help her with the preparation of the fish skeleton. 

so after deboning the fish skeleton, i soaked it for a while in detergent and left it to dry outside with a serving tray below. probably because there were still pieces of food left on the bones itself, the cat jumped on the tray from the 11th floor right after i left it in the sun. the tray wasn't held nor fastened so together with the tray, the cat fell all the way to the ground floor. the cat did not survive.
