5 Things to Consider While Buying a Cat Door

·  Durability 

While buying a cat door, you’ll have to ensure that the cat door you’re buying is durable. Because nobody wants a broken cat door in their house and put their safety at risk.

But unfortunately, there is no exact way of measuring the durability of the cat door. For this, you’ll have to trust the other pet owners or read our reviews. 

·  Installation

After durability, you’ll have to look at the ease of installation of the cat door. If you buy a high-quality cat door, but it’s difficult to install, there is no point in buying that.

Besides, if you need professional help to install the cat door, it’ll add up to your costs. That’s why before buying a cat door, read the manual carefully and check what tools are required.

·  Size of the Flap

If the flap size of the cat door is smaller than your cat’s width, your cat won’t be able to move through the cat door. That’s why while buying a cat door, you’ll have to ensure that the flap size of the cat door is large enough for your cats.

To find out the accurate flap size, first, you’ll have to measure the width of your cat and add an extra inch to it (this is the width of the cat door). 

After that, measure your cat’s torso height and chest size and add an extra inch to it. This will be the required height of the cat door.

·  Security 

Different cat doors offer different security options. You’ll have to decide which one will be perfect for your cats.

For example, some cat doors open freely, which allows all animals to go through the cat door. However, this can be a bit risky for your cats because if there are aggressive or stray animals near your house, they may enter your home and harm your cats. 

If you’re concerned about your neighbor’s aggressive pet, you can install an electric cat door. This type of cat door will only allow your cats to move through the cat door. As a result, other animals or pets won’t be able to enter and harm your cats.  

Again, there are some cat doors, which allow only one-way access. For this type of cat door, you may have to train your cats a bit. 

·  Color and Shape of the Flap 

As cats have a wider body, you should buy a cat door that has a square flap size. Again, while buying a cat door, it’s better to buy a cat door that is full or semi-transparent.

Because when the flap is transparent, your cats will know where they are heading and give them an outside glimpse.
