I can't stop hurting my kitten
What is your reason for hurting your kitten?
I really am not sure what is giving me the urge to do this.
You should not be abusing your kitten. By having a pet you signaled you want to be responsible for its well being.
I'm going to be a responsible pet owner and make sure she has food and a warm place to sleep
It is great that you now want to start taking proper care of your cat. Just know that your cat will be much happier if you start treating it better in this way.
