Everybody loves cats. Or at least they should. Kitties may be aloof and independent, but they are also sweet, affectionate, and make great companions. Even so, no one can deny that kitties can be quite willful creatures. They love to roam, explore, and have access to all the hidden places in the house. Cat doors, portals, and tunnels are an ideal way to allow your cat the freedom of movement through and in and out of the house without having to keep your doors always open. This is especially important for the bathroom – your cat can do its business even when the bathroom is closed. 

Cat doors come in all shapes and sizes. They are usually flaps, but can also be tunnels, portals – and simple holes in the wall. As each one has its pros and cons, it can be quite a challenge to pick out the perfect one for you and your cat. To help narrow the search down, we are bringing you the 10 best cat doors on the market.

It features a robust and durable plastic frame that can be mounted quickly and easily with just four screws. The hole is covered with a thick tinted plastic flap that won’t let light in.

As a cat owner, you were probably wondering whether or not cat doors are necessary in your home. Of course, at the end of the day, they are not necessary per se. But when you consider all the advantages they bring, you will quickly understand that they are a valuable accessory to have in your house. 

For example, when the bathroom is closed but the kitty needs to do the business, you will be roused by the scratching and meowing. And then you need to get up – often during the night – to open the doors. Of course, leaving the doors open all the time is not ideal: you risk drafts, smells, and dirt escaping through. In this case – and many similar ones – a cat door comes as an invaluable helping hand. 

Cat doors give your feline friend a much-needed dose of independence in the home. They can move freely from room to room and even venture outside if that is an acceptable option for your area. Still, you have all the necessary control over their movements. Most cat doors rely on a 4-way locking system that allows you to finetune the directions your cat can take. Portal cat doors on the other hand are much simpler and are a great choice for multiple rooms. Just put one on each wall you want and forget about closing and opening the doors. 

Some advanced cat door designs rely on microchip ID in order to let your cat pass. This prevents any strays or curious neighborly kitties to barge right into your home. If that is a problem you experienced before, these doors are ideal for you. 

In the end, it’s clear that a cat door – in whatever shape and size – is a great thing to have in the house. It gives you some much-needed peace of mind and lets you focus on crucial daily tasks. And, of course, your cat will absolutely love the independence a cat door gives them!
