Glass Cat Door Installation Sydney

Fitting a cat door into a glass panel is not the same job as fitting one into timber or a screen. The glass has to be identified correctly, cut to a precise diameter, and sealed properly, and getting any of that wrong means replacing the panel. Sydney Paws Petdoor has been installing glass cat doors across Greater Sydney since 2010, and the work is done by a glass cut-in technician rather than a general handyman.

Most cats sit at a closed sliding door and wait. A cat flap in a glass door removes that entirely. Your cat comes and goes on its own, the door stays shut, insects stay outside, and you keep the option to lock the flap when you want the cat in for the night.

Cat Door in Glass, Cat Flap Installation

If your sliding door or window is laminated glass, our technician cuts the opening on site and installs the Pet-Tek Catwalk cat door into the panel where it sits. The panel does not come out of the frame. That is the difference between a straightforward installation and a full glass replacement, and it is the main reason a glass cat door installation costs less than most people expect.

Toughened or safety glass cannot be cut once manufactured. For those panels we have a pet door specialist glazier fabricate a new panel with the opening already in it, then swap the panel out. Either way you end up with a cat door for sliding glass door that works, and we tell you which situation you are in before any work starts.

Pet-tek Catwalk Cat door comes with 3 years warranty. Click here to find out more about Microchip Cat Doors today.

Cat Door for Sliding Glass Door

The Catwalk fits 99% of glass sliding doors and glass windows in Sydney homes and is the only cat door on the market designed specifically for sliding glass panels. The unit sits in the panel itself, so the door slides as it always has.

Clearance matters on ranch sliders. Provided your sliders have the required gap between panels, the slimline Catwalk or Dogwalk sits clear and does not interfere with the slide.

Pet-Tek Catwalk Cat Door Specs. Cat Doors in Glass Doors

The Catwalk is a translucent circular flap moulded from polycarbonate, one of the toughest materials available for this application, and UV stabilised so it does not yellow in the Australian sun. Visually it reads as part of the glass rather than a bolted-on fixture, which matters when the panel is the main feature of a living area.

Cat Door For Sliding Glass Door

  • Four-way locking system, in, out, both, or closed
  • Flap size 195 x 185mm
  • Full weather seal with moulded feather edge to limit draughts and rain
  • Automatic magnetic flap positioning and quiet action
  • External self-draining condensate outlet
  • No-cavity design, so dirt does not collect inside the glass
  • All stainless steel fixings, fitted with four screws
  • Suits glass panels 3mm to 20mm
  • Cut-out diameter 267mm
  • Recyclable

Cat Door Sizes for Larger Cats

The Catwalk is rated to 8kg, which covers the majority of domestic cats. For cats above 8kg, the Pet-Tek Dogwalk Mini installs into glass the same way and is rated to 13kg. We measure your cat’s shoulder height and width on the day rather than guessing from breed.

If your household has more than one cat, or a neighbourhood cat that lets itself in, a microchip cat door reads your cat’s existing chip and stays locked to everything else. We also install timber cat doors and screen cat doors where the glass panel is not the right entry point.

FAQs – Got Questions About Installing a Cat Door in Glass?

Yes, if your existing glass panel is laminated, we can cut and install the cat door on the spot without removing the glass from the frame. If it’s toughened (safety) glass, we’ll replace it with a custom-made panel designed to fit the door.

Absolutely. The Pet-Tek Catwalk is specifically designed for sliding glass doors and fits 99% of them. As long as there’s at least 0.8mm clearance between panels, the door will continue to slide normally.

We use the Pet-Tek Catwalk and other cat doors, which are translucent, circular flap made of UV-stabilised polycarbonate. It’s weather-sealed, secure, and blends in seamlessly with most modern glass doors and windows.

Yes, we can install glass cat doors in both glass doors and windows. We’ll assess your existing glass type and panel size to determine the most suitable solution.

I had a great experience with Sydney Paws Petdoor. After I left a message on their website I received a call. I found the call very helpful and accommodating. They were out the next day and did a tremendous job. Both were very professional and punctual and I will be referring their company to others without hesitation .

We had put getting a pet door in the “too hard / too expensive” basket for a long time, but finally decided to go for it. Sydney Paws Pet Door were fantastic from the start. Super fast responding to our enquiry and getting a quote through, really reasonable pricing, and they were able to come out to the Central Coast in good time. It was installed today and we’re really happy with it. The product is great and actually looks really good too. Really happy we finally got it done. Great service, great product and definitely recommend!

Alex was awesome- professional and really skilled at installing and communicated the pros and cons of using different doors. Really loves and cares about what he does and spent the time to help us retrain a 14 year old dog who is semi blind and deaf to use the door in our new home we just moved into. I would have had no idea what to do had he left without helping me train Max. By the afternoon Max was using the door all by himself. Highly recommend to anyone looking for an installer who truly cares

Totally a 5 star service in every way! We had a medium pet door installed in our folding glass door and it looks awesome and works great. Alex and his team are such great guys to deal with and were happy to accommodate our personal needs as well providing excellent service, advice and tips for how to get our silly cat using the door properly. Really could not have asked for a better result. Thanks Alex and Allen!!!

8 months ago we had our pet door added to our house. Summer was amazing in getting our appointment arranged. Alex arrived on time and installed our new pet door quickly and efficiently. He gave us great training on how the door worked and patiently showed our fur babies how to use the door. Our boys use the door all the time, often at running speed. The door still looks great and is as strong as the day it was installed. Highly recommend Summer, Alex and the team for your pet door solutions.
Excellent job done Alex. Thank you for the lovely services
Response from the owner:Thank you, Shyamalee! We really appreciate your kind words — Alex will be so pleased to hear you’re happy with the service. It was a pleasure helping you! 🐾

Response from the owner:Thank you, Holly! We’re so glad you had a great experience. It was a pleasure helping with both the glass and timber install, and we really appreciate your kind words about the team. Thanks for the recommendation!

I can’t recommend Sydney Paws Petdoor enough. I had no idea what I needed or wanted and Summer was very helpful sending me information and pics of options as well as set pricing that made the whole process super easy. Alex came same day and did a fabulous job. He’s a super nice guy and gave me all the pros and cons about the two places I had chosen as options for the door to be installed which made it easy to determine the best solution. He even did some training with us and our dog and talked us through the best way to get him to use it.
Response from the owner:Thanks so much, Tamara! We’re really happy we could make the process simple and help you choose the best option for your home and your dog. Alex always enjoys walking owners through the pros and cons and helping with the training too. We appreciate the lovely feedback and recommendation! 🐾

Summer and Alex are an absolute dream team to deal with – I can’t thank them enough for squeezing my booking in and making the installation during the consultation. Could not be happier and Billy 🐺 took to the door like a natural (which is awesome if you know how stubborn huskies are at the best of times) Thank you for making our day with the smooth and tidy fitting and installation… 5 stars ✨ Sydney Paws Petdoor
Response from the owner:Thanks so much, Mark! We love hearing this — Summer and Alex will really appreciate the kind words. So glad we could fit you in and get everything sorted on the spot. And Billy 🐺 taking to it straight away is a huge win (especially for a husky 😄). Thanks again for the recommendation!

Great service, quick installation, and Alex even trained my dog on how to use it. My dog is 8 years old, stubborn, and has never used a dog door before so I was genuinely concerned she wouldn’t take to it – but she did, and in record time too. Very happy and highly recommend!
Response from the owner:Angela, thank you so much for this lovely review! We’re so glad your girl took to her new door so quickly—especially at 8 years young! 🐶💛 Alex loves helping with the training side of things, and it’s always so rewarding to see even the most stubborn pups succeed. We really appreciate your recommendation and hope you both enjoy the new freedom!

Amazing service! Our door was installed on the day we made the inquiry and they even showed us how to train our (very reluctant and stubborn) dogs to use it. Highly recommend for pet door installations in Sydney.
Response from the owner:Thank you so much, Danielle! We’re thrilled we could get everything sorted the same day and help even the most reluctant pups feel confident using their new door. 😊 Really appreciate the recommendation — it means a lot!

Faultless service! The communication from Summer was excellent. Prompt and detailed responses. She even managed to squeeze me into an earlier appointment slot. Alex was wonderful to deal with – friendly, courteous and great attention to detail. He gave good recommendations about the sizing and happy to patentially explain his thoughts. He even cleaned the glass and gave toilet training tips for my puppy. I would recommend them to everyone.
Response from the owner:Thank you so much, Janice! We're thrilled to hear everything went smoothly. Summer always does her best to make booking easy, and Alex takes great pride in the small details — from sizing to training tips. We're so glad your puppy is off to a great start with the door. We really appreciate your recommendation! 😊🐾
