There's nothing more to be said that others haven't. You absolutely MUST get that kitten out of there. If you feel you can't do anything, or don't feel you can call the Humane Society, go to your parents or a teach or counselor at school. This "friend" definitely has some emotional problems if she puts a kitten in a dryer and turns it on! Then laughs at it!

This is absolutely animal cruelty and I really believe if you don't do something to get the kitten out of there it will not live very long.

Please if you feel you can't do anything, get adult help. This kitten needs you to intervene immediately!

And once you save the kitten, it might be best if you don't socialize with this "friend" anymore. Anyone who treats an tiny defenseless animal like that doesn't have a lot of respect for life in general and it would probably be best if you stayed away.

And I'm sorry if some of the responses here seem cruel to you, but there is literally a life on the line here, and it's up to you to save that little kitten! Don't wait, do something NOW!!!! before it's too late.
