What to Look for in the Best Cat Doors
What you look for in a cat door depends on your specific needs. Do you want to give your cat a space safe away from your dogs? Are you looking for a door that lets your feline friend outside when needed? Do you need a door that can keep the weather out? Or are you looking for a cute indoor cat door?
Size
Before searching for the best cat door, first, measure your cat. The right cat door will provide plenty of space for your cat to enter and exist freely.
When measuring your cat, measure the widest part of your cat and the height. Add about two inches to both measurements to find the desirable cat door size. Cats are more agile than dogs; therefore, precise measurements aren't as important for cat doors as for dog doors.
Door Type
There are a few types of cat doors. Some are designed to be installed on the interior, and some are designed for the exterior. Some can be installed on any type of door, and others can only be installed on a solid one. And if you have sliding doors, there are cat doors that are designed to fit into a track of sliding glass doors or a sliding door with a screen.
Exterior Doors
A cat door typically doesn't let a lot of cold air come through. However, if you live in a cold or harsh climate, you may want to get cat doors designed with an installation that can trap the draft.
Interior Doors
Many interior cat doors are open passages with no flap. Some of these doors even feature an easily stained frame, so you can paint it to match your interior door.
Design
You can choose from a range of cat door types, including double flaps, insulated pet doors, automatic, and smart or microchip-activated cat doors. A microchip-activated cat door is the most expensive option, but it works with your cat's existing microchip and keeps stray or wild animals out.
Locking Mechanism
A cat door is designed to provide easy and convenient access for your cat, but there are times when you don't want your cat to leave.
For whatever reason you are getting a cat door, many cat doors feature a locking mechanism. Some have a plastic piece that slides down and prevents the flap from opening. A four-way locking is also more advanced and provides more control. It allows you to set your cat to enter only, exist only, enter and exist, or have no access. The most advanced option in the cat door is the magnetic closure. It uses a magnetic one on your cat's collar or a microchip to open the flap.
Installation
Installing a cat door can be a little tricky but doable, as it does involve some drilling and a jigsaw to cut the shape of your cat door. Depending on the type of cat door you purchase, it's best to check with the manufacturer's instructions for the best way to install it.
Price
You can find most cat doors cost anywhere between $30 to $200. The cost can vary depending on the type of door you choose and the material.
FAQs
How do I install a cat door?
To install a cat door, you will need:
Drill with a 3/8-inch or 1/2-inch drill bit
Jig saw
Measuring tape
Pencil
Measure the distance from the bottom of your cat's stomach to the floor. This is approximately the space you should place at the bottom of the cat door from the floor.
Remove your door from its hinges and set it on two sawhorses or your workstation.
Place the template on the door, using the measurement from Step 1. It's recommended that your cut should be at least 3 inches from any edge of the door.
Tape the template in place and use a pencil to trace around the template.
Using the drill, make a hole in each corner of the template. If you have a metal door (common for exterior doors), you'll need to use a drill bit specifically designed for this material.
Start in one hole and use the jigsaw to cut straight from one corner to the next. Follow the template as closely as possible. Repeat until you have cut out the opening for the cat door. For metal doors, be sure to use a jig saw that is intended for use on metal.
If you're using a self-framing cat door, insert the interior and exterior sides of the cat door frame. Read the manufacturer's instructions and install using the included hardware.
If you're not using a self-framing door, you'll need to cut four pieces of wood to match the dimensions of your door. Attach them to make a frame, and install it before installing the cat door.
Can You Install A Cat Door To Window?
Yes, you can install a cat door into any pane of glass if it's large enough to fit the door. There should be at least 50mm of space all around.
Can You Install A Cat Door To A Sliding Door?
Yes, you can! You will want to consider a narrow design to fit between the door and window.
How To Get A Cat To Use A Cat Door?
Whether your cat will use it will depend on your pet. With positive reinforcement, you can encourage your cat to go in and out of the door and help to get your cat comfortable with the cat door.
