Is there such a thing as a draft free cat flap?

I am going to be bricking up a door when the weather gets better and will be re-positioning a cat flap here.

I was thinking of perhaps using two cat flaps. One inside and one outside to minimise drafts, but is there a real draft free cat flap?

Well, an air-lock arrangement would be best, but that would require a sufficient gap between the two doors that the cat cannot hold them both open simultaneously. So you would need to add a tunnel outside.

Of course, if you had a sufficiently brush-like cat, it would minimise the air flow by occupying most of the space as it entered. Perhaps some sort of perm?

I use a magnetic cat-flap and that's pretty draft proof. The flap itself remains locked firmly shut until my cat comes along and opens it with a magnet in his collar.

I assumed the OP had the sort of cat that stands halfway through the cat flap peering in or out, and that this was when the drafts occurred. If not, then your solution ought to be fine. Perhaps a refinement would be a very gentle mechanical boot up the cat's arse in the direction it is heading...

My current one is magnetic in that it has a magnet attached to stop the door flapping in the wind, but cold air still gets past as it is not airtight in any way.

I might create a tunnel when I brick up the door and have one flap at each end.
It will also be inside a new floor to ceiling cupboard that I will be creating so that will probably help as well.

I have a tunnel with my cat flap as it goes through the wall

its a microchip catflap which is brilliant as it only lets her into the house and no other cats and its very draft proof - its a Staywell Petsmate one

I currently have a Staywell one, but suspect it is one of their cheaper models.

When ready, I will carefully select what I need.

Thanks for all the suggestions.
