Get your minds out of the gutter, people. She was talking about cats.

The relevant passage from Julia’s Cats: Julia Child’s Life in the Company of Cats (Abrams Image):

Pussycats. Before Paris, Julia admitted that she had never really known cats, but “since Minette and other French cats, I just love pussies.” In the decade after Paris, Paul’s job meant they were always being uprooted, so she couldn’t have a cat to call her own, but every time she saw one, she fell under the old spell. Alley cats and strays or the feline friends of friends—she couldn’t resist scooping them up and giving a squeeze. Each one reminded her of Minette and those magical days at Roo de Loo.
