My hamster just died.
How did your hamster die?
I did not provide the necessities of life for it.
You bought the hamster so you must take care of it. Not feeding your hamster is irresponsible. When you don't feed your pets, they die.
I didn't buy it. It was given to me.
It doesn't matter how you got it you need to take care of it. It suffered before it died and that's really wrong of you do to.
