These textless comics are more open to interpreation than most, but behold my personal headcanon if you like, and ignore it at will:
My headcanon is that Catalina was actually trying to address Lucy's complaints about how her shirt wound up after Rhoda transformed her, and even left off the dog part of Golden Cheerleader. She also figured Rhoda would like it, but still.
Catalina did not, however, think to leave off the mental effects, which includes cheering, perkiness, and acting somewhat doglike. Nobody present objects to this oversight.
