Introduce your cat to the flap prior to when it's set up so they can be familiar with the size and shape. Open the flap and let them explore it from all angles.
Make sure the cut-out is level and square. Mark the screw holes and align them with the cat flap opening. The distance between the edges must be the same.
Preparation
A cat flap in your home is beneficial to the health and well-being of your pet. It allows your pet to move from the inside to the outside, without needing to allow them in or out. It can also prevent them from fighting over cat food, litter boxes, or the door of the home.
The first thing you'll need to do before starting the installation of your cat flap is prepare the area where it will be placed. This is because eliminating any obstacles from the area will make it easier to work. It is also important to take out any furniture or decorations that could get in the way of your work.

A good spot to put the cat flap is in a door that leads to an enclosed space like your closet or laundry room. This will prevent the cat from jumping over it and will allow you to keep the cats from any potential dangers. The flap should be low enough for your cat's smallest to use, since taller cats may struggle to jump through a flap that is higher.

It is a good idea to hire an expert handyman if you have a sliding door or a windows with sash that are old-fashioned. It isn't easy to install the cat flap on these windows and doors and any mistakes can cause costly damage. A professional can install the cat flap in a safe manner without damaging the structural strength of the door or window.
You will need to measure the height of your cat's belly from the ground in order to mark the flap's location. This will allow you to accurately cut the opening for the flap. Once you have the line drawn using a spirit level, you can use it to ensure it is horizontal. Then, go through the directions included in the cat flap kit to locate the template. Attach the template to your door, so that the bottom edge is in line with the horizontal lines you've drawn. The template should be placed in the middle of your door.
Measurement
A cat flap, also referred to as a dog's door, is a small opening at the bottom of external doors or windows. It lets pets get in and out of the home. You can pick from a variety sizes and materials to find the perfect one for your pet.
Before you purchase a cat flap, it is important to accurately measure the dimensions of your doors or window in which you plan to install it. You can then be sure that the cat flap will fit and the hole is the right size. You can use this technique to determine the width of the opening by securing off a section and walking through it with your pet.

If it's too low, they might struggle to get through. If it's too high, they may not be able to use the flap.
Generally, you should drill your holes at 45 degrees to the vertical surface. This will ensure the most secure and stable installation of your cat flap. If your cat flap kit didn't include a spirit level, a straight edge could be used in place.
When putting the cat flap to glass or UPVC door or window it is recommended to hire an experienced glazier to complete this for you. This is due to the fact that these types of doors are typically toughened and drilling into them could damage the integrity of the glass and could lead to it shattering in the future, which could be a security risk for your home.
It can also be difficult to install a cat flap inside brick walls, as drilling into a soft section of the wall can create problems for cables and pipes that run through the property. This can lead to expensive repairs, or even leaks and weather damage caused by the outside.
Marking
Once you've measured your cat kitten to determine the correct size flap then you need to mark the location where the hole needs to go. Mark the centre of the flap using your spirit level. If the template for your cat flap kit does not include the centre line, copy it and draw around it with pencil to mark the location where the hole needs to be cut.
Remember, if the cat flap is too low, it can make it difficult for your cat to climb in and out of your house, and if the flap is too high, they could struggle to see what's going on outside. It is recommended to make it close to your cat's belly as you can to give them the greatest comfort and security.

Then, prop the door open and encourage your cat or kitten to enter it by pointing out where they should go (it helps if someone's on the inside to help them). Once they've walked through it then you can gradually begin to let them in and out at will.
It is important not to push your kitten or cat through the flap at a high speed because this can cause them to be scared. The clunk, snap, and squeak of the door closing can cause injury to your cat or kitten. They'll be more scared if their tail is stuck in the flap. Cats also tend to return home to check for invaders, so leaving the door open at this time could pose a risk as it can lead to your pet being attacked by another cat they are familiar with. Installing the door for your cat is best for your cat or kitten if it knows how to use it.
Installation
It is important to show your cat how to use the cat flap after it is installed. This will take time, but with patience and a few treats to entice them, they will eventually get habit of it. You may also want to install a lock on the flap for extra security, particularly during harsh weather conditions or when away from the house.
The first thing you need to decide the location you'd like to place the cat flap inside your door. It should be placed in a location that can open up to an area of protection in your garden. This will allow your cat to feel more secure when they move into and out of your house, and also to keep other animals from entering your home.
You should also take into consideration the height of the flap for your cat. This should be in the same area as the measurement of your cat's belly to ensure that they can pass through with ease. It is also possible to put steps on either side of the door to assist your cat navigate it with ease.
After you have chosen the location you would like to put the cat flap take a measurement of the door and mark it with the pencil. This will give you a guide for the best place to cut. The next step is to cut a square out of the door with an jigsaw. Wear safety goggles, and a dust mask to protect your health from inhaling dust. After cutting the square, it is necessary to smooth the edges of the door to create smooth edges.
After you've finished sanding, now replace the cat flap inside your door. You should put the cat flap in such that the lock (if there is one) is positioned on the inside of the door. If there are holes for screws for the cat flap on the door, then drill them into place. Then, you should carefully insert the flap inside the hole, making sure that it is snugly in place.
