We need a new back door and it makes sense to have a double glazed one. We also have (sigh) four cats and this door is the only one suitable for the little darlings to enter and egress.
To me the obvious idea is to have a non-glazed lower panel and the flap in that. If I am not deluded this must be a reasonably common request. Is it ? Any advice or experience (must not be catricide) will be gratefully received.
TIA,
Dave.
