Why Install a Cat Door?

A cat door is a smart way to give your feline companion the independence to explore, sunbathe, or return home without relying on you to open the door. It helps reduce stress for both you and your cat — especially if they meow to go in and out multiple times a day!

Modern cat flap installations include features like microchip recognition and magnetic locks, adding security while ensuring only your cat has access to your home. Whether you have a curious kitten or a seasoned prowler, it’s a great long-term solution for flexibility and peace of mind.

What to Consider Before Installing a Cat Door

Not all cat doors — or homes — are the same. Before committing to installing a cat door, here are a few important things to think about:

  • Glass type and location: Double-glazed or toughened glass panels may require replacement with a suitable safety glass unit.
  • Your cat’s size and behaviour: Some cats are hesitant, while others love to roam. Choosing the right size and style (manual vs microchip) matters.
  • Access control: Microchip cat doors can be programmed to lock at night, or only allow certain pets in or out—ideal for households with multiple pets or indoor/outdoor restrictions.

We work with a range of quality cat door brands and models, including:

  • SureFlap Microchip Cat Doors
  • PetSafe Manual Cat Flaps

Frequently Asked Questions

Can you install a cat door into double-glazed or toughened glass?

Yes, but there is a distinction to make — we can install a pet door in a new piece of toughened glass or double glazed glass but we cannot retrospectively install a pet door in your existing double glazed or toughened glass door. Our team is fully trained in handling all types of double glazed and toughened glass.

How much does cat door installation cost in Christchurch?

Pricing depends on your glass type, the cat door model, and whether a replacement unit is needed. We offer free, no-obligation quotes so you know what to expect upfront.

Do I need a microchip cat door or a manual flap?

Microchip doors offer better control and security, ideal for multi-pet households or busy areas. Manual flaps are simpler and more budget-friendly. We’re happy to help you choose the best option.

How long does the installation take?

Most installations take an hour to install, depending on what pet door product is required. A trip to complete measurements for the cat door may be required and lead times vary for different products.

Will the cat door compromise the insulation or safety of my home?

Not at all. We install cat doors into custom glass units designed to maintain insulation and comply with NZ safety standards.

Do you install cat doors into wooden or aluminium doors too?

Our focus is on glass door installations, but feel free to contact us—we may be able to recommend a suitable installer for other materials.
