This is my adopted sister Panthor. (Her name is a combination of "Panther" and "Hathor.")
Mom and dad kept us separated for the first weeks after I arrived, and introduced us slowly. Because I am so much older, my energy was intimidating to her at first.
We've gotten into a few swat-fights, and even though she has claws and I do not, I wasn't going to take any guff from this youngster!
We coexist much better now, but I don't suppose we'll ever be cuddle buddies. :-/
