Every pet parent knows the constant routine of playing doorman for their pets. Cats meowing at the back door to explore the backyard, or dogs whining to go out for bathroom breaks just as you sit down on the lounge. Installing a dedicated pet flap is one of the most practical home improvements you can make, offering independence for your pets and peace of mind for you.
At Pet Shopee Australia, we understand that finding the right balance between convenience, home security, and weatherproofing is crucial. In our range of cat and dog flaps, you will find modern designs built for Australian homes. In this guide, we break down the different styles of pet doors, how to measure your pet accurately, and key tips for easy installation and training.
The Key Benefits of Installing a Pet Flap
Adding a cat or dog flap to your home does more than eliminate constant scratching at doors. It delivers real lifestyle and wellbeing benefits for both pets and owners:
- Fewer Indoor Accidents: Dogs can relieve themselves on their own schedule, which is particularly helpful when you are working long hours or stuck in traffic.
- Mental and Physical Health: Free outdoor access allows pets to soak up sunlight, exercise, explore their environment, and reduce boredom-related destructive behaviours.
- Emergency Safety: If an unexpected event happens indoors, such as smoke or a loud disturbance, your pet has a safe escape route into an enclosed backyard.
- Protecting Your Doors and Screens: Eliminates torn mesh screens and claw-scratched paint on wooden door frames.
Australian Climate Note: During scorching summer days or cold winter nights, look for flaps featuring dense brush seals and dual magnetic closures. These features prevent conditioned indoor air from escaping and keep Australian flies and mosquitoes outdoors.
Popular Types of Cat and Dog Flaps in Australia
Pet doors have evolved far beyond basic plastic swing flaps. Depending on your home layout and security needs, here are the primary types available:
🚪 1. Standard Manual Pet Flaps
The classic two-way or four-way locking manual flap. These units allow pets to push through whenever unlocked, and feature simple slide-locks or rotary dials for locking overnight.
- Best for: Secure, enclosed backyards with no stray animal concerns.
- 4-Way Lock Modes: In only, out only, open both ways, or fully locked.
- Pros: Affordable, simple mechanism, requires zero batteries or power.
📡 2. Microchip Activated Pet Doors
Microchip pet flaps read your pet’s existing identification microchip (or an RFID collar tag). The door unlocks exclusively when your registered pet approaches and locks immediately once they pass through.
- Best for: Homes troubled by neighborhood cats, possums, or other outdoor wildlife entering uninvited.
- Multi-Pet Support: Most models store up to 30 to 40 individual pet chips in memory.
- Pros: Unmatched security and complete prevention of intruder animals.
🪟 3. Glass Fitting Pet Flaps
Many modern Australian homes feature large glass sliding patio doors. Glass-fit pet doors feature circular or slim profiles designed specifically for insertion into glass panels.
- Best for: Glass back doors, sliding patio doors, and full-length windows.
- Installation Note: Toughened safety glass cannot be cut on site. A glazier must measure the door and supply pre-cut toughened glass with the flap hole cut out prior to tempering.
🛡️ 4. Screen Door Pet Flaps
Given the popularity of security screen doors and flyscreens in Australia, screen door flaps clamp directly onto wire or mesh security grilles, providing easy backyard access while keeping main glass doors open for fresh air.
- Best for: Security screen doors, flyscreen patio doors, and laundry access.
- Pros: Easy DIY installation, budget-friendly, maintains natural ventilation.
🧱 5. Wall Tunnel Pet Doors
If your doors are unsuitable or you prefer an out-of-sight entryway, wall tunnel kits allow pet doors to be installed through exterior brick or timber walls with telescoping tunnel liners.
- Best for: Properties where modifying glass or primary entry doors is not an option.
- Pros: Clean aesthetic, flexible positioning in laundry or garage areas.
Pro Tip: Renting your home? Look into temporary patio sliding door inserts that slip directly into your existing sliding door track without any cutting or screw holes. Discover quality choices in our pet flaps collection at Pet Shopee Australia.
How to Accurately Measure Your Pet for a Flap
A common mistake is buying a pet door based only on weight. Two 10kg dogs can have completely different body shapes, like a long, slender Whippet versus a broad, stocky French Bulldog. Always measure your pet directly:
📐 1. Measure Shoulder Width (Flap Width)
- Measure your pet across the widest point of their shoulders or chest using a ruler or tape measure.
- Add an extra 3 to 5cm of clearance so they can pass through comfortably without brushing against the frame.
📏 2. Measure Chest Depth (Flap Height)
- Measure from the top of your pet’s shoulders (withers) down to the bottom of their chest or belly.
- The top of the pet door opening should sit at least 2 to 3cm higher than the tallest point of your pet’s back.
🪜 3. Step-Over Height (Installation Height)
- The bottom of the door frame should sit comfortably low, roughly 5 to 10cm from the floor.
- Ensure senior pets or dogs with hip dysplasia and arthritis do not have to lift their paws excessively high to step through.
Step-by-Step Guide: Teaching Your Pet to Use Their New Flap
Some confident pets push through a flap immediately, while timid cats or cautious dogs may need a little encouragement. Follow these gentle training steps:
🐾 Step 1: Prop the Flap Open First
Use masking tape or a peg to prop the flap completely open for the first couple of days. Let your pet inspect the opening and get used to passing through the hole without any plastic touching their head.
🍖 Step 2: Use Positive Food Motivation
Stand on the opposite side of the door with their favourite high-value treats or meal bowl. Call their name gently and reward them warmly each time they step through the opening.
🚪 Step 3: Lower the Flap Gradually
Once they walk through confidently, let the flap hang loose. Gently push the flap open a fraction with your finger, show them a treat, and encourage them to push past the flap with their nose or paws.
Training Rule: Never shove or push a hesitant pet through the door. This can scare them, cause the flap to snap against their tail or back, and create a lasting fear of the door.
Home Security and Maintenance Checklist
- Overnight Locking: Use the built-in locking panel or 4-way lock every night to ensure outdoor safety and adhere to local Australian cat curfews.
- Clean the Sensors: For microchip and infrared pet doors, wipe down the optical lens and internal frame tunnel monthly with a damp cloth to prevent dirt from blocking chip readers.
- Inspect Weatherstripping: Check the soft fuzzy brush seals around the edges of the flap every six months to guarantee proper insulation against outdoor drafts.
- Boundary Fencing Check: Ensure your perimeter fencing, gates, and boundary latches are completely secure before unlocking free backyard access for your pets.
Frequently Asked Questions
Can a pet flap be installed into existing double glazed glass? +
You cannot cut a hole directly into existing double glazing or toughened glass without shattering the pane or breaking the sealed vacuum. A qualified glazier must measure your window or door and order a brand new custom double glazed unit manufactured with a pre-cut, factory sealed cutout for your pet flap.
Will other animals or neighborhood cats enter through my pet flap? +
With standard manual flaps, curious neighborhood cats or native wildlife could push through if the flap is left unlocked. If unwanted animal visitors are a concern in your suburb, investing in a microchip activated pet flap guarantees only your microchipped pets can enter.
Can a cat and a dog share the same pet flap? +
Yes, provided the flap is sized to accommodate your dog and the door swing is lightweight enough for your cat to easily push open. For large dogs and cats, a medium to large door can work for both, or you can install separate access points if your cat prefers a smaller, secluded flap.
How do I stop drafts and rain from coming through the pet door? +
Choose pet doors that feature built-in magnetic edge catches and dense perimeter brush seals. These seals snap the flap closed firmly after your pet passes through, keeping out strong wind drafts, rain, and insects.
Can a puppy or kitten use an adult-sized pet flap? +
Young pets can use adult flaps if the bottom step-over height is low enough for their short legs. Ensure the flap is lightweight or prop it slightly open until your puppy or kitten gains sufficient strength and confidence to push through the magnet resistance.
