When you first get your cat door installed, training your kitty to use it can initially be a challenge. They’ll see it there, but probably will be confused as to what to use it for. Just as with training them to, say, use their litter box for the first time, you’ll notice that your cat will want to ease into it.

What is the Best Cat Door?

Training Your Kitty to Use the Cat Door

If your cat is curious, he may walk over to the door several times, tap the flap with his paw, and simply watch it swing before actually going through it. At first, the moving flap may be making him nervous and hesitant to use his new cat door. So, consider leaving the flap off of the door for a couple of days after you first put it in. Without that obstacle in the way, chances are your kitty will leap through it, and begin to feel a lot more comfortable going in and out. Cats enjoy their freedom, and having a door just for them to enter and leave as they please will make them very happy on a daily basis.

After about 48 to 72 hours, replace the flap, and see how your cat reacts. If they go through it like they are supposed to, then give them a reward. Learning to use a cat door is a big accomplishment, and your kitty needs to realize that they are doing something good. So, if they have a favorite treat, give it to them. Or, if they enjoy playing a certain game, spending that time with them after they successfully use their cat door will reinforce the learned behavior.

Remember, having patience is the key. Younger cats will sometimes take longer to learn to use the door, so you may end up leaving the flap off for a day or two longer with those young felines. One trick you could use would be to take a little time every day standing on the other side of the cat door with their favorite toy or treat. This will entice them to hop through, and after a while your cat will have developed a good habit of using the door, even without you standing there.

It’s important that you choose the best door in your home that’s the most fitting and convenient for your new cat door, because once its cut, it will be there for good. For example, if you want your cat to, say, use a litter box in the basement, you’d install the door where there will be easy access. But remember, your cat will be hopping through it freely after a while, so it’s not recommended that you install it into a house door that has steps directly behind it like some basement doors do. Sure, the old saying is that cats always land on their feet, but if you have owned yours long enough you know that this isn’t always the case. A set of stairs directly behind the door could possibly injure them badly.

That being said, you also don’t want to get a door that is too small. Doing so could very well result in your kitty hitting its head on the top part, or bruising its legs. A general rule to follow would be to get a cat door that is a couple of inches bigger than your cat. For example, if yours has wide shoulders, and they are the widest part on the cat’s body, you should base the size of the cat door opening on the shoulders, and buy one two or three inches wider.

How To Install Your New Cat Door

When you get your kitty’s new door home and open it up, you’ll notice that there is a template for you to use. This will be what you trace around with a pencil onto the door, and you should be sure that you are putting it in the exact spot you want it because, again, after cutting the hole there is no going back! It is recommended that you trace around the template at least three inches from the bottom of the door that you are about to cut into.

After tracing, you then need to mark the places where the screws are going in with the pencil, that’s if your cat door requires screws. Most times on cat doors screws are used to hold the outer part of the door together. After removing the template, you now will need to mark an X where you will be drilling. In the four corners of the square you just traced, use the pencil to put a small X in each one.

The best tool to use for drilling is a drill bit of about 3/8 for the screws. But, this is not always the case, and sometimes a different size is recommended, depending on the manufacturer and brand of cat door you chose. The small X’s you marked in the four corners will normally best be drilled with a 1/2 inch drill bit, but, again, it’s depends on the exact door you purchased. The size of the tools you will need can vary, especially on the newest model doors. So, be sure and read the instructions well before beginning to install it.

Now comes the fun part…It’s time to cut the door! Most cat owners find that using a jigsaw works best. This is because of the size of the blade as well as the fact that jigsaws normally cut straight and will allow you to precisely stay on the line you marked with the pencil. Pick one of the half inch holes you drilled, stick the jigsaw into it, and begin to slowly and carefully cut the door. You want to take your time when cutting the cat door, otherwise it could end up looking kind of sloppy at completion, and the interior frame may not fit properly.

Next, you will be placing the frame in the hole, and if it’s cut correctly it’ll be flush with your house doors inner surface. Then, you can begin to enter the screws in the appropriate spots. No need to tighten them too much, just a snug fit is fine. Afterwards, go around the outdoor frame with caulk to prevent air from leaking through.

Your kitty or kitties will love the newfound freedom that a cat door gives them. Now, all you need to do is choose the one that is best for your cat. Here are some of the most loved ones on the market.

Good for Hesitant Cats

You want your cat to have the freedom to go in and out at will, and yes, they do too. But, with the average cat door, there is a flap that your kitty has to use his head to push through.

Can Be Installed in Multiple Places

Just because it’s called a cat door doesn’t mean that is the only place pet owners consider putting it! For example, you may have a cat that, before purchasing the door, was used to going outside through a certain window in your home. So, why would you want to install your new cat door into a door? It would likely be hard to get your kitty to use it, especially if he’s been going in and out of that window for some time. That’s why the manufacturers designed this cat door for walls and windows as well.

  • Four-way lock system
