Logan, I am glad that Butter is calming down. When I thought about this I recalled that years ago Patches scratched and attacked when we first adopted her. And now, Rascal who is only three did the same thing when I first let him in the house with me. I certainly am not an authority, but I think part of it is just the "settling" in for a new cat. Who is in charge? What are the rules? At least for me, the consistency of good treatment, lots of love and a good home seemed to calm my cats down.
Once they felt secure they stopped the attacking.

Also let me be the (59th??- ha!) person to tell you that I love the name "Butter."
