I also hope that this won't continue! I think it wasn't an act of aggression, I guess it's only Luna's way to tell her that she had enough. She's also pawing at my hand when I'm petting her, and she doesn't want it.

As for the nail trimming, I'm already doing that from time to time. Luna's claws are growing too long, and then she has problems walking on carpets or blankets, that's why I started to trim her claws. Most of the time it works without too much protest from her. But you're right, I have to do that more often now, to protect Lily. I already did it this evening, and she accepted it.
