Yesterday she decided to climb up my side while I was in bed, pulled the cover off the top of my head, then BITE MY HEAD. I told her no, she stopped. For a second. Then did it again!! So I shook her off. She sulked by sleeping against my back so I couldn't see her instead of under the covers where she likes.
She is right now in Real Kitten Hours which is running, jumping, biting. Less biting though lately.
The Oxford comma is good but honestly the sentence should probably just be reworded to not require it. I use to be more hardline about it being absolutely needed.
