Ever wished your feline friend could enjoy the freedom of your entire home without constant supervision? Installing a cat door in an interior door can make this a reality. Not only does it provide your cat with independence, but it also allows you to control their access to certain areas. Let’s explore how to put a cat door in an interior door, ensuring a secure and functional fit.
Before you start, consider the size of your cat and the door. Standard cat doors are around 6.5 inches wide and 7.5 inches tall, which should accommodate most cats. However, if your cat is particularly large or small, you may need to adjust the size of the cat door accordingly.

Choosing the Right Cat Door
Selecting the right cat door is crucial for a successful installation. Here are two main types to consider:
Flap Cat Doors: These are the most common and typically use a magnetic closure to keep the door shut when not in use. They’re great for controlling access but may not be suitable for drafty areas or homes with multiple pets.
Manual Cat Doors
Manual cat doors, on the other hand, use a lever or a handle that your cat pushes or pulls to open the door. These are ideal for homes with multiple pets or drafty areas, as they can be locked when not in use.
Consider your cat’s age and agility when choosing a door. Older cats or those with mobility issues may struggle with manual doors, making a flap door a better choice.

Size and Material
Ensure the cat door is large enough for your cat to pass through comfortably. As for material, plastic and aluminum are popular choices due to their durability and ease of cleaning. However, some cats may prefer a wooden door for scratching.
Installing the Cat Door
Once you’ve chosen the perfect cat door, it’s time to install it. Here’s a step-by-step guide:
Measure and Mark
First, measure and mark the center point of your interior door where you want the cat door to be. This should be at a comfortable height for your cat, typically around 12 inches from the floor.

Use a compass or a circular object to draw a circle on the door that matches the size of your cat door. This will be your guide for cutting.
Cut the Hole
Using a jigsaw, carefully cut along the marked circle. Ensure the blade is suitable for the material of your door. If you’re unsure, consult a professional or the tool’s instructions.
Once you’ve cut the hole, test the cat door to ensure it fits snugly. If it’s too tight, you may need to sand down the edges slightly.
Install the Cat Door
Follow the manufacturer’s instructions to install the cat door. This typically involves attaching the door to the inside of the door using screws or bolts. Ensure the door swings freely and closes properly.

If you’re using a manual cat door, make sure the lever or handle is positioned correctly for your cat to use.
Training Your Cat
After installation, it’s time to train your cat to use the new door. Here are some tips:
Positive Reinforcement
Encourage your cat to use the cat door by rewarding them with treats or praise when they go through it. This will help them associate the cat door with positive experiences.
You can also try placing their food or litter box on the other side of the door to encourage them to use it.

Patience and Persistence
It may take time for your cat to get used to the cat door. Don’t rush them. Let them explore the door at their own pace and reward them for any progress they make.
If your cat seems scared or anxious around the cat door, try leaving it open for a while to let them get used to it. You can also try playing with them near the door to make it a positive place.
In no time, your cat will be enjoying the freedom of your entire home, and you’ll have the peace of mind that comes with knowing they can access certain areas when they need to. So go ahead, install that cat door, and watch your feline friend thrive in their newfound independence!
