Glass Fitting Cat Doors

Glass Fitting Cat Doors

The neatest way to give a cat their own entrance through a sliding door, patio door or window: a Catwalk® glass fitting cat door, glazed into a round hole in the glass panel itself. No frames bolted over the glass, no external screws — from either side it looks like the panel came that way.

The original cat door takes a 165 × 193 mm flap (width × height) in glass from 3 to 10 mm; the Maxi pet door steps up to 187 × 203 mm and handles glass to 28 mm — the pick for big cats, cat-and-small-dog households, and double glazing. Prefer selective entry? The multi-magnetic cat door opens only for your cat’s collar magnet and glazes in the same way, in glass up to 26 mm — the glass version is special order in Australia, so contact us to arrange one.

Not sure your cat fits the standard flap? Our cat door sizing guide covers the three measurements to take. Installation is a glazier’s job and a routine one — round cut-outs are exactly what the trade prefers, and our guide to what fitting into glass costs sets out the figures. Our installer directory lists people who fit these weekly, and the Find Your Fit tool confirms the right model before anyone cuts anything.

Glass Fitting Questions, Answered

How does a cat door go into a glass door?
A round hole is cut in the panel — before toughening, if the glass is toughened — and the cat door clamps into the hole, self-lining from both sides. Existing toughened or double-glazed panels can’t be cut afterwards, so the glazier orders a replacement panel with the hole pre-cut.
Can it go in a window instead of a door?
Yes — any glass panel of the right thickness works: sliding doors, French doors, fixed panes and windows. Choose a spot your cat can reach comfortably from both sides, and keep the flap’s bottom edge near your cat’s belly height.
Which model for double glazing?
The Maxi dual glaze takes units up to 28 mm and is the model we stock for double glazing. The multi-magnetic handles up to 26 mm, but the glass version of it is special order in Australia — contact us if selective entry matters more to you than off-the-shelf availability. The original cat door suits single glazing from 3 to 10 mm.
I’m renting — is this really an option?
It’s the classic renter’s route: the glazier fits a replacement panel with the door in it, your landlord’s original panel goes safely into storage, and everything is restored when you leave. You keep the door and the cut panel for the next home.
Will the neighbourhood cats invite themselves in?
Not if you choose the multi-magnetic model — the flap only releases for a cat wearing the collar magnet, though the glass version is special order here. On the standard doors, the 4-way lock gives you full control of when the flap works and in which direction, and our guide to stopping other cats coming through a cat door covers what else works.
How much does professional installation cost?
It varies with the glass — panel size, thickness, and whether it’s toughened — so get a quote from your local glazier or one of the fitters in our installer directory. Our cost guide gives you the range to expect. The door itself ships Australia-wide at a flat rate.
