Cats vs new front door

[Emochild]

I have 3 cats and a new front door

It's very well insulated and makes a wooshing sound when you open it

The cats are petrified of it

How long will this last?
It's there route of choice normally because it involves a human slave to stand up and open it rather than using the perfectly good cat flap in the back door but they are asking to come in then running off when we open the door

How do I teach them to chill out?

Unfortunately i'm a bad cat slave and I have run out of dreamies

I blame the fact that the dds are on school holidays so the cats are getting more dreamies than usual

They'll soon calm down if you stop the treats and the attention.

Harry was scared of our door when we first got it! It took him a while but, being the nasty person I am, he just had to get on with it, no special treatment for him!

My cats wouldn't go out of the front door or the patio doors. But the would scuttle in through them though. The back door, in and out, in and out, in and out no problem.
