Draught proofing a cat flap

[RhythmNBooze]

We have one of those micro chip controlled cat flaps for our 3 but the flap has a small gap around it so that when it's not being used a draught comes in. Has anyone used anything to seal it up a bit but without affecting the way it functions. Wondering about a brush type border thing.

I got my boyfriend to build a cat flap porch extension thing for my cat flap. So a wooden porch with another flap on it on a side facing wall (so wind can't blow straight through). Works a treat. But of course you can only do that if the flap is on a wall rather than a door.

Ours is in the door so that won't work unfortunately.

Email them and ask them. You can't be the first.
