My older cat, Piper was being a bitch to her little sister, Daisy, and then Daisy attacked me after I PROTECTED HER FROM BEING ATTACKED FROM PIPER, and then I put Daisy out in the living room, and kept Piper in my room. Once I got back in, I turned to look up at Piper[she is on my closet] and said "Your sister is gone, you whiny bitch"
