Riku, my first instinct was to repeat the comment
HOW THE HELL IS THAT NOT ANIMAL CRUELTY?!?!?!?!
but I calmed down and realized that it is harder for some people to make the commitment to get involved. Trust the majority of people and realize that you will actually be HELPING the girl with the kitten by helping her to realize what she is doing is SO VERY wrong. If she can do this to an animal, especially a baby animal, imagine what she can do later in life.
Sometimes the right thing to do is thr hard thing to do.
