"Entirely appropriate, to someone who wears so much leopard print, and is quick to show her claws."
However, after several tweets criticised him Mr Twyford issued an apology: "Alright @paulabennettmp I plead guilty in the court of twitter. Sorry for the claws."
Ms Bennett said in reply to a tweet about it that another Opposition MP had called out 'meow."
"What is the male equiv? I remember an aus politician having to publicly apologise."
When another tweeter asked if she was guilty of similar behaviour, Ms Bennett replied "labour like to stand of a staunch platform of women's rights but don't then practice them."
Ms Bennett has made a claw gesture and meowed herself in Parliament herself although in a different context. In 2012 Ms Bennett was wearing a leopard-skin pattern jacket and Labour MP Jacinda Ardern asked her if something was "all smoke, mirrors and camouflage." Ms Bennett responded by clawing the air and miaowing, and making an observation on Westie fashion.
On another occasion, she drew criticism for saying to Ms Ardern to "zip it sweetie."
It wasn't the only slight unusual exchange in Parliament.
NZ First leader Winston Peters was grilling Defence Minister Gerry Brownlee about whether the Army were doing pre-deployment training and Mr Brownlee replied that "it's simply speculation, much like the ferry touched the bottom."
That was a reference to Mr Peters' ongoing campaign over the Cook Strait ferries. Mr Peters replied "well, it touched your bottom, yeah."
He was not asked to explain.
