A Little Background

CatMouse was created as a fork of the popular Terrarium TV app by developer CatFiles. After Terrarium TV was shut down, CatMouse was developed from its open source codebase and has since surpassed the original with new features and improvements.

The app sees frequent updates to squash bugs, improve performance and add more content. CatMouse is not available on any official app stores, but you can easily download and install it using the Downloader app on your Firestick, Fire TV or Android TV box.

Why People Love CatMouse

With free movies and shows from Netflix, Prime, Hulu and cable channels, CatMouse provides endless entertainment for free. No wonder it has millions of happy users across the globe!

According to a recent poll on the official CatMouse website, over 80% of users switched from apps like Kodi, Cinema HD, BeeTV and other popular streaming apps. The reasons they cite include:

  • Huge library of 4K, 1080p and SD quality streams
  • Faster streaming speeds and fewer buffering issues
  • Slick and intuitive interface for quick navigation
  • Regular updates with more content and bug fixes
  • Advanced support for Real-Debrid and Trakt integration

Additionally, popular Firestick blogs like Troypoint, FirestickTricks, FireStickFans and TechDoctorUK all recommend CatMouse as the top movie/TV app in 2022 owing to its rich streaming sources, fast performance and ease of use.

Clearly, CatMouse brings together an unmatched combination of high-quality streams, fast streaming, and powerful integration features that makes it a favorite for casual and experienced streamers alike.

Now let‘s get into how you can get CatMouse up and running on your streaming device!

How to Install CatMouse on Firestick & Android TV

The process to download and install CatMouse is quick and straightforward. It should only take 5 minutes to complete.

Here‘s a step-by-step walkthrough:

Step 1) Turn on Apps from Unknown Sources

Since CatMouse isn‘t available on the Amazon App Store or Google Play Store, you need to enable installation of third party apps in your device‘s security settings.

On your Firestick or Android TV device, go to:

Settings -> Device Preferences -> Security & Privacy -> Allow Apps from Unknown Sources

Turn this ON. You may get a warning that this makes your device more vulnerable to unknown apps – don‘t worry, CatMouse is 100% safe when downloaded from the official site.

Step 2) Install the Downloader App

The Downloader app allows you to directly install apk files on your streaming device. Search for "Downloader" in the app store and install it.

Once it‘s installed, open the app and enable JavaScript when prompted on the initial screen.

Step 3) Download the CatMouse APK

In the Downloader app, go to the Browser tab. Enter the URL in the text box and press Go.

This will download the latest version of CatMouse in APK format on your device. The file size is about 20MB.

Once the download is complete, you will get a popup for starting the installation. Press Install to proceed.

Step 4) Install from the APK

After you select Install, you may get a warning that the app is from an Unknown Source – don‘t worry, just click Install Anyway or Install Now to continue.

The CatMouse app will now be installed on your Firestick/Android TV device directly from the downloaded APK file.

Step 5) Delete the APK File

Once the installation finishes, you will see the message "App Installed". Press Done to close the installation window.

Next, go back to the main Downloader screen. Here, press the Delete button to remove the downloaded CatMouse APK file from storage.

This cleanup frees up space on your device since the APK is no longer needed after installing CatMouse.

Step 6) Launch the CatMouse App

Go back to the home screen of your Firestick or Android TV. Head over to Apps and you should now see the CatMouse app icon. Select it to launch the app.

The first time you open it, CatMouse will ask to enable notifications and overlay permissions – agree to both. And that‘s it! CatMouse is now ready for streaming movies and shows.

Wasn‘t that easy? With just 6 quick steps you can have the amazing CatMouse installed on any Fire TV device, Android TV box, Nvidia Shield or other streaming gadgets.
