Step 1: Measure the Width of Your Window

Why This Matters
To choose the right cat door, you first need to know how wide your window is. The width of the door should fit well inside the window frame.
How to Measure:
- Use a measuring tape and measure from one side of the window frame to the other.
- Write down the number in inches or centimeters.
- Compare it with the size of the cat door you want to buy.

- Make sure your cat can easily reach it. If your cat is small or young, you might want to place it lower.
Real Tip:
“I put the cat door a bit higher because I didn’t want my toddler to play with it. But if you have a small cat, it’s better to place it closer to the ground.”

Before installing the cat door, check for any obstacles that might get in the way. Things like window locks or handles can make installation tricky.
How to Check:
- Look closely at your window for any parts that might be in the way of the door.
- Measure the space around the window to make sure it’s clear.
Real Tip:
“I almost bought a cat door without checking the window handle. It would’ve blocked the door from closing properly!”
Step 5: Choose the Right Door Size
Picking the Best Fit
Once you have your measurements, it’s time to choose the right size cat door. Make sure the door isn’t too big or too small for your window.
What to Look For:
- Small cats: Choose a door that is just big enough for them to pass through.
- Larger cats: Go for a larger door to make sure they fit comfortably.
