Yes — the entire Catwalk® glass fitting cat door range is designed for double glazing, ranch sliders and patio doors. A glazier cuts a round hole and the door slots in cleanly. Glass thickness 3mm to 32mm is supported. Read our full guide: cat flaps in double glazed glass.

Measure your pet's shoulder height and widest body width while standing, then add 25mm to each measurement. Use those figures against our size chart. Full instructions with diagrams are in our pet door measuring guide.

The permanent, battery-free solution is the Catwalk® multi-magnetic cat door. A small magnet on your cat's collar unlocks the flap — no other cat can open it. No electronics, no programming, nothing to replace. See the full explanation: how to stop other cats coming through your cat door.

Not with a Pet-Tek door. Every Catwalk® and Dogwalk® model features a full-perimeter brush weather seal and precision-moulded polycarbonate flap that sits flush and draft-free when closed. Read how Pet-Tek engineers out the cold: keep your home warm with a pet door.

A glass fitting cat door installs directly into a glass panel — a glazier cuts a round hole and the door fits flush into the glass. A wood fitting cat door installs through a timber, PVC or composite door panel — often DIY-friendly with basic tools. Pet-Tek offers both types across the full Catwalk® and Dogwalk® range.

Yes — ranch sliders are one of the most common installations for Pet-Tek glass fitting cat doors in New Zealand and Australia. A glazier drills a round hole into the sliding panel and the cat door unit fits directly into the glass. Most glaziers complete the job in under an hour.

Only for glass fitting installations — cutting glass requires specialist core drilling equipment and training. Wood fitting pet doors are DIY-friendly and most homeowners can install them in under an hour with basic tools. See our full cat door installation guide for both options.

Pet-Tek cat doors are built for long-term use. The UV-stabilised Bayer Makrolon® polycarbonate flap will not yellow, warp or crack — even in harsh NZ and Australian sun. All models come with a 3-year manufacturer's warranty and many customers report their doors still performing perfectly after 10+ years. Spare parts are available for the full product life.
