Bide your time. Ivy
It's pretty even between the two of them in terms of picking and winning fights. They're just playing here but last week Ralph got a sharp whack on the head for trying to make a move on a piece of bacon Ivy was eating incredibly slowly. He was honestly dumbfounded and it was so funny. Ivy has curious food favourites which so far seem to be limited to egg yolk and toast crumbs (she eventually abandoned the bacon), and not tuna/steak/chicken/ham/everything like Ralph.
