Wall Fitting or in a Glass Door

When choosing how your cat flap needs installing, these are two of the most popular options to consider:

Wall Installation:

  • This method works brilliantly; normally, your damp-proof course (DPC) sits below floor level—a common setup that poses no issues.
  • Can be fitted in a corner, without compromising the aesthetics of your room or obscuring the view of your garden.
  • Wall installations offer excellent durability and can be positioned at the perfect height for your cat. 

Double-Glazed Unit (DGU):

  • This approach involves fitting a new glazed unit with the cat flap already integrated.
  • It’s a clean, professional solution that maintains the integrity of your existing door frame.
  • I recommend that you keep the original DGU, as a spare unit or can be refitted if you move to a new property.

Both methods are perfectly valid choices, and we’re equally happy to carry out either installation based on what works best for your home. The key is choosing the right approach for your specific situation rather than being steered towards the quickest option! We believe in taking the time needed to do the fitting as required by you. Whether that’s 30 minutes to fit a DGU, or 3 hours for a wall installation. Our priority is both your needs and your cat’s safe-freedom

Just a couple of our Customer testimonials

What a great service! Delivered and installed in no time, clear glass, efficient and so friendly—much more pleasant than working with a big chain. The cat flap was fitted and looks amazing; brilliant job. I highly recommend this service. Tracie, northamptonshire


“I’m thrilled with the result; Colin fitted my cat flap today. It was quite an unorthodox installation (a cat flap through a wide pillar). As Colin was happy to discuss and find an unobtrusive solution that works aesthetically. I’m sure the cats will be equally happy!” – Sharon, East London
