Sometimes, when Watchcat Rosie and Watchcat Sammy had spats, they'd start licking each other, ostensibly lovingly at first, but then increasingly aggressively. Eventually, they'd start hitting each other. Finally, they'd put a paw on each other's heads to say, "Stop that."
It was always reassuring to see them settle their differences with that paw-on-the-head signal of a truce.
