I've been asked to install a catflap in a door that has the typical 2
glass panel arrangement. Think they are called 2XG or similar.

Does anyone know if there is an easy way to cut the glass in situ to
install the device, square hole or round?

My gut feeling is that the easiest option is to either replace the
existing glass with a bit of 4mm ply that I can easily cut or to order
a new piece of glass with the hole pre-cut (expensive?)

Thanks for advice.

Your local glass merchant will be able to cut a round hole - for an idea of
cost we got a full length double glazed toughened unit replaced on our patio
door (about 50cm * 200cm) with a catflap fitted (supplied by us) - inc
measuring up, fabrication and fitting cost £95 including VAT (Edinburgh
area)
