Cat Doors for Renters — The Fully Reversible Way to Install a Cat Flap

Q: Can I do this in an apartment?

If the unit has a private balcony slider or courtyard glass door, the same replacement panel method applies, but apartments usually need body corporate approval as well as the landlord's, since exterior glazing is often common property.

Q: Does the same approach work for a dog?

Yes. identical method with a larger cut-out, using the Dogwalk® glass fitting range.

Cat using a Catwalk G-SDDC glass fitting pet door

More cats live in rentals than ever, and "can I install a cat door as a tenant?" is one of the most common questions we get. The answer is yes, and done the right way, the property can be returned to exactly its original condition when you leave, with nothing for a landlord to object to and nothing deducted from your bond. This guide covers the reversible installation method, what to ask your landlord (with a ready-to-send checklist), and which Catwalk® doors suit each situation.

Key Takeaways

The glass replacement panel method is fully reversible: your original glass panel is stored intact and swapped back at the end of the tenancy.
Always get the landlord's written consent first; NZ tenancy law sets out a process for tenants requesting changes to the property.
You take the cat door with you when you move; the unit refits into a new panel at your next home.

The Reversible Method: Glass Replacement Panel

Most NZ rentals have a glass door or ranch slider, and that's the ideal renter installation, because nothing about the property is permanently altered:

A glazier measures the existing glass panel and orders an identical replacement with a round cut-out for the Catwalk® glass fitting cat door.
The original panel comes out intact and is stored safely (garage, under a bed; it's one sheet of glass).
The new panel goes in and the cat door is fitted and sealed; the door and frame themselves are untouched.
At the end of the tenancy: the glazier swaps the original panel back in. The property is identical to day one, and the cut panel plus your cat door move with you.

Sliders and modern glass doors are toughened, which means the replacement panel route is the standard installation method anyway; renting just adds "keep the original panel." The full process is in our glass fitting guide and the slider specifics in the sliding door guide.

Getting Landlord Consent

Under New Zealand tenancy law, tenants can ask to make changes to the property, and there is a formal process for those requests; see Tenancy Services: tenants making changes to the property for the current rules. Whatever your situation, get consent in writing before booking a glazier. A well-prepared request is very hard to say no to:

What to Put in Your Landlord Request

The method: "Replacement glass panel by a qualified glazier; the original panel is stored and reinstated at the end of the tenancy. No changes to the door, frame or joinery."
Who pays: you cover the door, panel and glazier, in both directions.
Who does the work: a professional glazier, not DIY.
The product: link the exact model page so they can see what's being fitted.
Reinstatement commitment: written promise to return the original panel at your cost when you leave, and offer to record it in the tenancy file.

Which Cat Door for a Rental?

Renter-friendly Catwalk® options, July 2026
Situation	Best Option	Reversibility
Glass door or ranch slider (most rentals)	Glass fitting cat door via replacement panel	Total: original panel swaps back
Neighbourhood cats sneaking in	Multi-magnetic cat door via replacement panel	Total: same method, selective entry
Timber back door, landlord approves cutting	Wood fitting cat door	Partial: hole remains; agree in writing whether the door stays or you replace the door leaf
Larger cat or small dog in the household	Maxi pet door (203×187mm flap) via replacement panel	Total

If wood is the only option, the honest position for the landlord conversation: the flap is removable but the cut-out in the timber is permanent. Some landlords are happy for a quality cat door to stay as a property improvement; others prefer you fund a replacement door leaf at exit. Agree it in writing either way. Not sure which flap size fits your cat? Use the measuring guide. Weather-tightness matters double in a rental, where the power bill argument can decide landlord consent: on a Catwalk® door the flap-to-body gap is machined to next to zero tolerance and closed by a full brush seal, so there is no daylight around the flap for a draught to find.

Moving Out, and Taking the Door With You

This is the part renters rarely realise: the cat door is yours and it's reusable. At the end of the tenancy the glazier reinstates the original panel, and your cut panel, if the next home's glass matches, or just the door unit itself moves with you. A new cut-out at the next place costs a fraction of a new door, and Catwalk® units are built to outlast multiple tenancies, with spare flaps and parts available for every model, including doors made 20+ years ago.

Frequently Asked Questions

Can a tenant legally install a cat door in NZ?

Yes, with the landlord's consent. NZ tenancy law sets out a process for tenants requesting changes to the property; check the current rules at Tenancy Services. Always get consent in writing before any work is done, and keep a copy.

Will installing a cat door affect my bond?

Not if it's done with written consent and reinstated as agreed. The replacement panel method returns the property to its exact original state, so there is nothing to deduct for. Photograph the original panel before removal and after reinstatement for your records.

What does the reversible method cost?

Three components: the cat door, the replacement glass panel, and the glazier's fitting time, plus the reinstatement swap when you leave. Costs vary with panel size and glass type, so get a quote from a local glazier with your panel measurements. Spread over a multi-year tenancy with a happier cat, most renters consider it well worth it.

My rental has other cats coming in from the neighbourhood: what stops them?

The multi-magnetic cat door: it stays locked unless your cat's collar magnet releases it, with no batteries or electronics. It installs by the same reversible replacement-panel method. More on the problem in how to stop other cats coming through your cat door.

Can I do this in an apartment?

If your unit has a private balcony slider or courtyard glass door, the same replacement panel method applies, but apartments usually need body corporate approval as well as the landlord's, since exterior glazing is often common property. Ask before quoting.

What if the landlord says no?

Re-present the request with the reversibility spelled out; most refusals come from assuming a hole gets cut in their property. If it's still no, options are limited to non-installed solutions (letting the cat in and out manually, or a window left ajar with its compromises). A written, fully-funded, professionally-installed, fully-reversible proposal gets a yes far more often than not.

Does the same approach work for a dog?

Yes. identical method with a larger cut-out. See dog doors for sliding glass doors and the dog door buyer's guide for model selection.
