By reading this guide you will be able to get this app on various devices including FireTV Stick 4K, FireTV 2nd, 3rd Generation, and even on a FireTV Cube.

To learn the whole installation method I would recommend you to keep reading this article until the end. It is because there are a few things that you need to know which will be described there. Other than this I will also share with you a method to update the CatMouse app.

This is why reading the whole process is recommended so you don’t miss any important information or else end up having some sort of problem. But before we move towards the installation section let’s learn about this app and the features that you get after downloading it.

What is CatMouse


the mouse is an app for Android devices that provides Movies & TV Shows free of cost. This app doesn’t contain any sort of advertisement neither it requires an account. It is also known as the clone version of a famous app known as Terrarium TV.

The reason is CatMouse was released after Terrarium TV went down and also offers the same user interface. But the truth is this app is way better than the old one as it works great with FireTV remote and offers a neat and clean interface without ads.

This app is full of cool and exciting features like you are getting an option to download a Movie or a TV Show to watch it offline. Other than this it also offers a subtitle feature so that if a user watches any movie in a foreign language can understand it too.

the mouse provides users with fast and premium links to stream content without buffering. However, if you are a Real-Debrid user then you can also integrate it to get even faster links. It also allows the integration of Trakt to keep your watch history.

Even though it provides several other features like using a 3rd-party media Player (VLC or MX Player), marking watched Episodes, notification for new episodes, and so on. This app is quite amazing to watch non-stop entertainment as the library updates usually.

How To Install CatMouse on Firestick

Once you learn about the features of CatMouse you surely get curious to download it. If that’s the case then don’t worry anymore since we are now moving toward the installation process. As I told you earlier that you need to read each step twice or if you don’t understand the step just check the attached screenshot instead.

Before we move to the installation section you first need to understand that CatMouse is not available on the Amazon App Store. That means there is no way to install it directly but fortunately, we still have an option to get it using the sideloading method.

To sideload an app there are several things required like Jailbreak, Unknown Source, and Downloader app. Once you have these things you are good to go but for those who don’t have these yet then first make sure to jailbreak your device following this guide: Jailbreak Firestick

After completing jailbreak you now need to enable the installation of Unknown Source. It is because by default Amazon doesn’t let users use any app downloaded from the internet. This feature is for security purposes so don’t misuse it or download the app from other sources.

You can enable the Apps from Unknown Source option by following given below steps:

  • Press and hold the Home button for a few seconds and then select Settings.
  • From settings find My FireTV and open it.
  • After this scroll down and select Developer Options.
  • It will show other options there so now hover to Apps From Unknown Source and press the select button.
  • A warning message will appear there and from there select Enable.

The apps from an unknown source are now enabled which means we can sideload CatMouse on Firestick easily.

Since two requirements are completed now only one thing is left which is the Downloader app. Basically, this is a free app for FireTV users that is used to download apps or can be used as a web browser. It has a nice and easy-to-use interface providing various features.

Downloader is officially available on the Amazon App Store which means it is completely safe to use. Now if you already have this app and you know the sideloading process then just skip this section. As this is only for those who don’t know much about it.

Ok, so let’s download Downloader app on a FireTV to install the CatMouse app:

Close all running apps and then from Home Screen hover to the above menu and select Search.


After this type of Downloader App (check screenshot below).


On the next screen, you will see Apps & Games Movies just stay on the Apps category and click the Orange Downloader icon


After this, you need to click on the Download (You own it) button.


Just wait for a while until the app is downloaded and then select Open to launch it.Install-CatMouse-on-Firestick

When you launch Downloader for the first time you will be asked permission to access Media, Files and Photos so when it prompts simply select Allow.


At this time you will get a notification window having Quick Start Tour Guide just ignore it and select OK it to dismiss.


Now you will notice a simple interface having a lightbox so hover to that box and press select to launch the keyboard there.


Using that keyboard type and then click on the Go button.


After clicking on the Go button it will start downloading CatMouse app you can see progress there.


Now simply wait for a while until the app is downloaded and when it completes you will see an installation window appears.


When that window appears just click on the Install button located at the bottom.


It will take a few seconds to install it and once the process is completed select Done.


After this, you will see the Downloader app again having a window with three-button so now click on the Delete button.


You will again ask for the confirmation and when it asks just select Delete again.

Now the CatMouse app has been deleted successfully and the backup file is removed. This is the recommended step as it helps in saving internal storage.

However, the official app is still installed and you can launch it by going to Your Apps & Channels > See All and here you will find all installed applications including CatMouse.

How to Update CatMouse on firestick

Since the app is already installed it doesn’t mean that this version will last forever, but instead, you need to keep it up to date. The developers of this app are working to bring new stuff, and new features, and fixes bugs and do some improvements through an update.

In this way, if you don’t want to face any problems or want to get new features then make sure to update CatMouse to the latest version. Although updating this app is quite simple as compared to others because you will get directly a notification and the update will be downloaded automatically.

However, if you don’t receive a notification or the app is not updating then you can simply follow the above guide instead. It is because we always update the link of the app so our users get the latest app with new features and new content.

But keep in mind you cannot install the update over an existing app so first uninstall the old version and then install the new app.

This method is quite lengthy and hard to follow because we don’t receive a notification that’s why we don’t know when we should update it. In this way, I would suggest you use an alternative App Store called Aptoide TV for Firestick.

It is the best app store that provides thousands of free apps to watch free content. Aptoide TV is compatible with the TV layout and is designed for FireTV. You can read this article to install this App Store on your TV: Install Aptoide TV Apk on Firestick

After installing Aptoide TV check out below quick steps to update CatMouse:

  • Launch Aptoide TV on your device and then hover to Discover.
  • Now use the right navigation key to access Discover content and it shows the list of the installed app.
  • From here you will notice a new menu with Updates Available, hover over it and select the CatMouse app.
  • At this time click on the Install button and your app will start downloading.
  • Once the app is downloaded an installation window will appear automatically so now select Install.
  • It will take a few seconds to install and then select Open to launch it.

This is how you can update CatMouse on Firestick using Aptoide TV within a few minutes. It is the best choice for those who want to get some free apps. Because we don’t need to type a long URL either we need to use Downloader.

CatMouse Alternative For FireTV Stick

CatMouse is the best app to watch Movies & TV Shows without buffering in HD resolution. But the problem is sometimes you may not be able to watch a Movie or else the link is not valid. At this point using a CatMouse alternative would be a good option.

There are hundreds of alternatives that are available on the internet but we are only talking about the top three best similar apps that are still working. I have checked these apps that’s why I am listing them here as most of the apps are shut down or stopped working.


UnlockMyTV is a new application released a few months after CatMouse but it gets too much fame in little time. Many users are watching their favourite movies and TV Shows through this app as it has a library of thousands of free content.

Just like CatMouse it also supports the use of an external media player including VLC, MX, and One Player too. Furthermore, this app has a good user interface that works with FireTV Remote and even on any other device like wireless keyboard, etc.

UnlockyMyTV is the best option for those who don’t speak English as their first language because it has the option to change the app language. Instead of this they also enable an option to watch any foreign movie with subtitles that are available in several languages.

Cyberflix TV

UnlockMyTV and Cyberflix TV are quite similar to each other or you can say these are like clones of each other. The layout is similar to that app which means without any doubt it supports FireTV remote and other wireless devices including the Console remote.

With the help of this, a user will get thousands of free Movies and hundreds of TV Shows from different channels. The best thing about Cyberflix is that it allows users to watch TV Shows according to channels like you will find Netflix, Hulu, and Prime series there.

Cyberflix provides fast links to its users to watch any content without interruption but still, you can use Real-Debrid with it. Integrating it will provide more quality links and even you will get links in 4K resolution.

This is the easiest guide that you can follow to install CatMouse on Firestick within a few minutes. I have mentioned each step along with screenshots so users can understand it clearly. Other than this when the installation is completed you should keep this app updated.

I have mentioned three possible ways how to update CatMouse so if you have missed it then simply go above and check it. Furthermore, you will also get some best alternatives to this app in case you didn’t find the movie or TV show that you are looking for.
