A big thank you for posting this, I’m forever googling ‘UK double flight cage’ and find just the one item:
Elegance Double Metal Large Flight Cage - Little Pet Warehouse
,which IS almost 1/2 the price but still not my ideal, due to the central bar and the fact that I have the single version of the cage and know from experience how much debris escapes the very shallow bottom tray.
This new cage seems to tick lots of boxes, it even has horizontal bars
, just need to start saving up now!
