I'm adopting a cat and have just bought a Sureflap magnetic flap with draught proofing. I've just got it out of the box and there's a small gap all the way around the door. There is a tiny strip of draught proofing material but I can feel a draught coming through if I blow on it.
The only place I can put the flap is in our patio doors next to the sofa. Will I be able to feel a gale blowing through it all winter? Does anyone have a recommendation for a flap with better draught proofing?
