Does the Sureflap flap in the wind, and can I just fit it in the same hole?

[Moln]

Sitting on the couch with the cat flap swinging constantly due to the wind.

I'm assuming the sure flap doesn't swing in the wind?

Should I get the expensive! Sureflap? it obviously has the advantage to keeping other cats out, not that that's happened yet..

I suppose it wouldnt as it's locked all the time. Cat flaps are a nightmare for draughts.

It's really windy here at the moment, no draughts at all with the sureflap. I imagine it should go in the same hole, the measurements are online, I think, so you could check.

I have sure flap and its gale force here and no flapping it just stays shut,

We have a Sureflap in central Europe, where it can get REALLY cold and windy in winter, and it's never 'flapped' in the wind or let in a draught, but there is something of a draught from underneath, so I presume there was a small gap in the wall left by the guy who installed it. As our cat can't go out at night, in winter we put a blanket in front of the flap as insulation every night.
