Is it possible to put a cat flap in a floor-to-ceiling glass patio door?
It’s virtually impossible, because patio doors are – or should be – made from safety glass and would shatter if you cut them, says Alan Barnard of the Glass and Glazing Federation (ggf.org.uk). ‘Patio doors come in two types of glass: toughened and laminated. The former would shatter like a car windscreen; with the latter you need to score both sides before cutting – tricky, as the glass consists of two panes and you can’t access the inside cavity. It’s easier and cheaper to replace your door with one with a cat-flap already fitted. Make sure it’s circular: cutting right angles into glass puts too much stress on it. And you can’t have the flap too close to the edge for the same reason, so make sure your cat is nimble enough to reach a higher flap.’ Try Everest (0800 010123; everest.co.uk) or Anglian (0800 500600; anglianhome.co.uk).
