    "New unit would have to be made with an aperture to the cat flaps dimension, you cannot cut into your existing unit."

    Not sure but I would contact a company that specialise with PVC doors as they will have to cut the glass to fit a cat flap."

    There are more variables that you would imagine here. If you want the cat flap to go through the glass you will need to order glass with a hole already cut into it as a door will be toughened glass and you are unable to cut it. There are other options but I would need to see some photos to see if they would work in this situation.

    Kind Regards,

    "This will cost around £80 because you will have to replace the glass unit. You cannot cut the glass as it's toughened."

    "Hi not advisable you need the correct cat flap or you can damage the integrity of the door

    "Realistically you wouldn’t want a cat flap in a glass door do you not have another door that is either solid or at least one with plastic as a filler? This would be more suitable."

    "The catflap is probably about £30 that would take roughly about two hours so two hours work you’re probably looking at another £30 so in total about £60"

    "You could remove the glass and replace with PVC board and then install cat flap. Costs could be up to £200."
