Fitting a Cat Flap in a UPVC Door

Allowing your cat to come and go from the house at its own pace is a great idea to keep it physically and mentally stimulated. A flap can reduce the frequency of accidents due to toilets, making it easier for the cat to leave the home when needed.
Take a measurement of the door
A cat flap allows your pet to come and go whenever they want without having to open the door. This makes it perfect to keep them in the house when you're at home or away and helps keep unwanted pests from the house as well!

Before you take any action, though, take a ruler and determine the width of the door in a variety of locations along its edge. You should also take measurements of the height of the door in a few places. This is because a door that is too high can cause your cat to do an exercise routine like a gymnast every time they need to use the flap!
Ask a glazier for assistance in case you're not sure what to measure for the door. They should be able to assist you in determining whether or not your door is suitable for a cat flap, and advise you on the right size of flap you should purchase.

If you have glass doors, it might be best to delegate this task to a professional glazier. It isn't easy to fit a cat-flap into an existing pane. It is also possible that it cracks and loses its weatherproof seal.
