Give your dog or cat the freedom they need by installing a doggy door at home. The best part about these portable options is that you don't need to change the door or cut a hole – separate panels slot into your existing sliding/patio door. Genius! Especially if you're renting. Here's how to install your pet door.


1Check your portable dog door kit is complete

Before you get started, open the kit box and check you have everything listed on the side. You'll need to make sure you have the top and bottom halves and the vertical joiner pieces. Get everything out, lined up and ready to go.

2Attach joiner to the base

For this bit you'll need a Phillips head screwdriver – if you don't already have one, head over to Bunnings and pick one up – they're super cheap and come in handy all the time. Attach the joiner pieces with the screw and the screwdriver – this is what's going to connect the top piece to the bottom piece.

3Put the two pieces together

If you're not very tall, you might want to get someone to help you with this step. Simply slide the top bit into the bottom bit and then tighten with screws. Turn around and repeat on the other side.

4Place dog door in your doorframe

Once your portable doggy door is in place, release your locking screws – it'll spring up and lock. The pet door should fit neatly in the frame with some tension on the spring-loaded section, but you can add an extension part if you need to. Tighten the top locking screws.

5Watch your dog or cat discover their newfound freedom!

Stand on the other side of the door with a treat to coax them through – this works really well, especially with food-orientated dogs. If you're using your doggy door for a cat it may take longer for them to discover it. If they're happy for you to pick them up, try manually putting them through to show them how it's done. If this doesn't work, try placing their food on the other side of the door when it's dinner time – their tummy will get them moving! Once they've done it and realised it's harmless, there'll be no stopping them! But remember to close the door at night to keep your kitty in.
