The gates are 23 inches high to prevent the cat from hopping over. Additionally, it includes rubber bumpers to avoid leaving any scratches on the walls.

  • You can place the door anywhere inside the house.
  • Carrying it, and placing it elsewhere is easier considering the lightweight.
 Things I don’t like
  • Though it is easy to fit the gate in, this also has a major drawback. On applying minimal pressure, the gate breaks open, and the cat continues doing what they do.

  • Furthermore, in an attempt to expand the gate, you could actually hurt your fingers.
  • The gate is not large enough to set up in hallways.
  • There are no instructions on how to use the product. As a result, it can be difficult to figure out how to use the locks and the levers.

A cat door,that can be installed into a wall or your door is the perfect way to help your cats visit the litter box without a dog or small kid bothering them. You can rest easy knowing the cat won’t escape. The door comes with two locks; one on the inside, and another on the outside. It should be mentioned that as per the flap size it will be easy for cats under 15 lbs., to get in and out without any trouble. The hard flap and plastic frame are built with the cat’s comfort in mind. PetSafe also provides a set of instructions to install the door.

  • Unfortunately, the size of the door is not suitable for a large adult cat.
  • There are some gaps around the door, which let the bugs get in.
  • Despite what PetSafe claims, this door is not meant for hollow interior doors.
  • Over time, the lock stops working, and it can then be dangerous because the cat can escape anytime.
  • It isn’t sturdy enough to stick to the door, and as a result, it falls off.
  • If your door isn’t 1/2 inches thick, you’re in for some trouble.
  • When the cat goes in and out, the door makes a creaking noise which can become annoying.
  • The magnets used to keep the flap from blowing by the wind is useless, and it only makes more noise.

Moreover, kitty pass notes that customers can paint over the product so that it matches to your house. Additionally, they believe it takes roughly 10 to 30 minutes to install the door. Customers are provided with a guideline and template to cut the door. In a clean and smooth cut, the door is the easiest and “cutest” pet door. The frame is designed in a curve to avoid any sharp edges that could injure the cat.

 Things I really like
  • You won’t face any issues if there are hollow doors back at your house.
  • As the material is partially plastic-wood, it is easier to make the curve and fit into the whole.
  • There is no noise when the cat goes in and out through the door.

  • Kitty Pass provides a template to help install the door, but the template is actually larger than the arch. Due to which, I would recommend not using a template.
  • You get 3m strips that are of no help. The door doesn’t hold on, and it falls off. You may have to screw it to the door.
  • As there is no flap, even the smaller dogs can easily get through.
  • It is a bit smaller for larger cats; they can’t fit through the door.
  • The product is a bit expensive, but it’s not a concerning con if you are okay with all the pros.
  • The corners of the product are not rounded off, and it could injure a playful kitten as they run in and out.

Another of PetSafe’s wall entry door makes it to our top five because of the great design. They bring you a unique door which can be installed to various walls such as; brick, siding, and stucco. This cat door is hailed as one of the best wall mount doors in the market. It should be noted that the door was initially made for both cats and dogs. It is also available in various sizes, such as; small, medium, and large. The key features mentioned are for the medium product; you can find details on their official website or Amazon page. This door is accompanied by a telescoping tunnel for walls that are about 4.75 to 7.25 inches thick.

  • A great pro is that you won’t have to buy earplugs with this door.It doesn’t make a whisper as the cat get in and out.
 Things I don’t like
  • The magnets for the flap don’t work, and you’d have to worry about something getting in or out of the house.
  • Majority of the frame is made out of poor quality plastic that can break easily. Only the cover of the product is made out of aluminum.
  • The door is certainly not easy to install; it can be a hellish task. While fixing it up, you will need to treat it gently in order to avoid breaking the frame or inner tunnel.
  • To make matters worse, once it is installed, taking it out is even more difficult. The toggle bolts are not so easy to remove.
  • Weighing the pros and cons to each other, this is certainly not worth the cost.

  • Lock: 4-way lock

Depets large cat door is also available in two other sizes (medium and small). The feature which sets this apart is an option to use a switch that is used to lock the door. Allow me to explain; the lock feature has four options;

  • No in & No out (Fully locked)
  • Free in & Out (Fully open)
  • In only
  • Out only

Additionally, the door includes a brush strip that is meant to cancel out any noise. Moreover, the door’s exterior is made with waterproof material to increase durability. To create more ease for customers, the door is very easy to install in windows, cupboards, and windows.

  • Honestly, at a price it’s available, the door doesn’t do such a bad job. However, It isn’t that great either.
  • There really is no noise when the cats go in and out.
  • It is great to have a variety of options thanks to the unique lock feature.
 Things I don’t like
  • Despite the large size option, the door is not large enough for a large-sized cat.
  • Basically, the lock is useless; it pops off the moment you fix it up.
  • The door will not swing at all, or it will stay open for the cat to come and go as it pleases, while the door steadily closes.
  • I wouldn’t really blame the company, but my sneaky little cat managed to figure out how to use the switch.
  • It’s a good idea, but the product is made out of poor quality. The flimsy plastics aren’t effective locks.

  • Some doors are hollow, and the majority of pet doors are not suited for them. So, when this came along, it was a welcomed surprise.

  • You will have to cut the ears, which is difficult to cut in the door.
  • When you open the door, this pet door will scrape through the ground. This can be easily avoided by a quick cut around.

  • The four lock feature is not meant for everyone; some people just want a simple cat door.
  • The magnetic strip isn’t strong enough to keep a hold of the flap. It is also necessary to properly close the door.
  • It may vary from one batch of the product to others; there is a possibility that you will get a cat door where the magnet is too strong for the cat push through.
  • The difficulty to use the door might also be due to the thick brush.
  • A poor quality frame may break while you are trying to fit in the screws.
  • It makes a lot of noise as the cat goes in and out.
  • The low quality of the product is frustrating as the plastic is easy to break. It isn’t durable enough to last six months.

You can find the ruff-weather door in four sizes; small, medium, extra-large, and super large. This review is based on the super large size.

 Things I really like

  • The ruff-weather door is made with better quality.
  • In terms of cost, the door performs better than most doors in the market.

  • Due to the weak magnets, the flaps could easily open with a breeze from outside. Hence, defeating the weatherproof purpose of the product.
  • Also, the rainwater tends to run down the flap, which is again a flaw directly opposing their weatherproof claim.
  • It makes a loud noise as the cats get in and out.
  • To make matters worse, the flap gets tilted and stays that way.
  • Installing the door takes too much time and effort because the size of the door might be too big for some walls. Or, in some cases, the nails are too small for the door are either missing or too small.
  • Eventually, the flaps will come off, and you’d have to get a replacement that is pretty expensive.
  • The two flaps make it difficult for the cat to get through the door.

  • The battery can last for a really long time.
 Things I don’t like
  • As the door is available in two sizes only, if you have a medium-sized cat that doesn’t fit through the small door, you’d have to pay up and upgrade to the bigger size. The option of another size would’ve been preferred.
  • Once the battery runs out, you can’t use it until the new battery is put into the door.
  • At times, you may have to reprogram the key to make it work.

Why is A Cat Door Necessary for Your Home?

You can install a cat door to avoid the hassle of opening and closing the door every time your cat wants to take a trip outside. Getting a cat door has numerous benefits, one of them being; convenience, as explained earlier. Other benefits include;

  • You can place the litter box on the other side of the door and no longer suffer from the odor.
  • The cat can roam around outside and do what it wants rather than stay indoors and scratch out the furniture.
  • With an automatic cat door, you can protect the cat from other feral animals.
  • The ability to explore outdoors can be a great physical and mental exercise.

Step by Step Process of Installing A Cat Door

Most of the times, people find it difficult to install a cat door, even if they receive a set of instructions from the company. From my experience, I summarized the following steps could help you install a basic cat door.

  • First and foremost, find the tools you will need to install the cat door. This may include screws, nails, hammer, screwdriver, jigsaw, driller, tape, etc.
  • Second, you can use the template provided by the company and trace it out on the door. Now, you will unhinge the door and use the jigsaw to cut out the traced shape.
  • Third, you will have to install the door frame simply.
  • Lastly, put the door back on its hinges and let your cat use the door freely.

It is important to note that some things will change when you are installing a complicated door (i.e., electronic door) into a wall or a window.

DIY – How To Build A Cat Door At Home

Sometimes it can feel impossible to find the perfect cat door, so let me ask you; why not make a cat door at home? I would advise you to find a pet door at amazon, but in the event that you want to make one at home, I got you! So, here is how you do it;

  1. Measure the cat
  2. Pick out two identical frames from the market or old ones that you don’t use
  3. Cut the door according to the outline of those frames
  4. Block the gaps if you have a hollow wall/door
  5. Nail the frames
  6. (Optional) Buy a flap or make one at home using a rubber mat

Note, this is a guide to making a cat door inside. There is a way to make a cat door for windows too, but we can talk about that some other time.

Does My Home Need A Cat Door

The personality of the cat can greatly impact this decision. A cat that is lazy and prefers to stay indoors doesn’t necessitate a cat door. On the other hand, if your lazy cat does leave a pungent odor after a trip to the litter box, a cat door might be just the solution you are looking for. Alternatively, a cat door could be helpful while parenting a young active cat that likes to jump around. It is also recommended for pet parents of cats that like to explore. Moreover, you can use a cat door to let aggressive cats go out and vent out. Getting a cat door is surely beneficial; it is an option that can help you benefit you either way. However, I couldn’t truly find a situation which necessitates a cat door. Keeping that aside, I would recommend you to get a cat door.

Training The Cat to Use the Door

Cats are odd creatures, they could quickly jump to the cat door, or they may require some training and time to learn to sue the door and get used to it. To train a cat, you can resort to the traditional methods like using a toy or a treat to motivate the cat. In some situations, the cat is actually frightened by using the door. It could be the sound the flap makes when the cat goes in and out. In such situations, you will have just to give the cat time to get comfortable with the door. My one advice in such situations is; be patient and let the cat take all the time it needs to use the door.

Things to Keep in Mind When Selecting A Cat Door

Every cat needs a different type of door suitable for them. So, when you are on the lookout for a new cat door for your home, there are a couple of things you need to keep in mind. What are these things? Read them below;

  • Type of door (is the cat door to be installed in walls, windows, or interior/exterior door)
  • Installation (is it easy to install)
  • Size (cats of different sizes would require a different size of cat door)
  • Flaps (are the flaps stable fitted perfectly?)
  • Material durability (how long does this material of the door last)
  • Location (where to put the door)
  • Weather (do you want a door that keeps the weather from ruining room temperature at home)
  • Features (weatherproof door, electronic door, what features are you looking for?)

These are some of the things that can help you make a better decision in terms of what type of cat door is best for you.

Related Questions

How much does a cat door cost?

The cost of a cat door starts from $25; you’d get an easy to install cat door with a plastic flap. If you want something fancier, the price could go up to $150 or even as high as $1200. What’s the difference here? The $150 door would be for larger animals with some other helpful feature. The other higher costs are attributed to electronic cat doors.

Do cats use pet doors?

Initially, you’d have to train the cat to use the door. This will require some time and patience, let the cat learn at their own pace. If you’re lucky, the cat might not need any training at all. And eventually, if you ever get another cat or dog, they’d naturally start using the door. Train one of them, and let the rest fall in line.

How big does a cat door need to be?

As cats come in various sizes, there is a different door size for each cat. For instance, a small-sized cat that weighs up to 8 lbs would need a 5 1/2″ x 7 1/2″ door to pass in and out. Alternatively, a door size of 6 1/2″ x 9 1/2″ should suffice for medium to large-sized cats.
