Depends on the animal you use, or the politician you insult

Labor says meowing or barking or whistling at a woman Senator is "schoolyard politics":

Tasmanian Liberal David Bushby made a loud “meow” noise to Senator Wong, who then accused him of sexism and “schoolyard politics”. 

“Oh yes, why don’t you meow when a woman does that? That’s a good idea,” Ms Wong said during the fiery exchange… 

Human Services Minister Tanya Plibersek labelled the Opposition Leader and his frontbench as sexist. 

“I think everyone in this house agrees there is room for humour, but what I am tired of and what so many women are tired of, is that whenever there is conflict, we have the Leader of the Opposition and his senior ministers reverting to this sort of sexist language,” she told Parliament.

But I'll rush to defend the Coalition with this example:

Bob Hawke today said, "Now I don’t mind Tony [Abbott], he’s not a bad bloke, but as I said during the [election] campaign he’s as mad as a cut snake…"

 Gotcha. Right back at ya, Labor Party.
