Hi,
I've got a problem: Bubz' cat flap is sticking and I'm baffled as to how to potentially remove the current flap in order to put a new one in. It was so well put in the double brick thickness wall that there aren't any loose points to start.
Is there any way to de-hair the so-called insulation strip that goes the length of the flap?
* I'm saying 'I' but on a physical level I'd have to get someone else to do it for me as I am unable to do these things myself.
