Some years back, i used to have a cat in my family house. The worst thing was that my baby-sister(was 3years old then) never liked it.

Whenever she sees the cat,she will rush to the it,carry it, and throw it into a drum of water. She continued doing this to the extent that the cat also hated her and when it sees her, it'll run off.

The last thing she did to it was that one day, she rushed and carried it, and threw it off the house from our balcony to down stairs.

I think the cat had had enough and ran away from there and never came back.
