Warning! Protect Yourself With A VPN

Most cord-cutters use a VPN and rightfully so.

The free streaming applications, addons, and paid IPTV services that you use are usually hosted on insecure servers.

Without a VPN, your IP Address is being logged.

Your IP Address points back to your location and identity which compromises both your privacy and security.

Your current IP Address is – When you use a VPN, your real IP address will be converted into an anonymous new one.

A VPN will provide you with an anonymous connection to the Internet.

This will prevent your Internet Service Provider, app/addon developers, government agencies, and any 3rd party from logging what you’re accessing online.

The most popular VPN among cord-cutters is IPVanish due to their blazing fast speeds and zero log policy.

Its important to use a VPN that is fast since we are streaming large HD files.  Its also crucial to find one that keeps no logs of what their subscribers access while online.

Setting up IPVanish VPN on your streaming device is simple!

CatMouse APK Description & Details

Since CatMouse is a fork of Terrarium TV, it will feature the same layout/format as this retired app.

This includes Categories for Favorites, Popular, New HD Releases, Top Rated, Trending, Recently Updated, Premieres, and all Genres.

As stated above, CatMouse features real-debrid integration for anyone who uses this premium service. This is a great way to ensure your streaming is buffer-free by pulling in the highest quality links.

Note: If you receive a reCaptcha error message, this can easily be disabled within the app’s Settings.

Another great aspect of this app is the option to add a account. This will ensure you never lose your spot in a movie/tv show by syncing and scrobbling your media across all devices and apps.


Subtitles Setup

IMPORTANT NOTE: While CatMouse’s built-in video player works great for streaming Movies and TV Shows, we have found it does not work for subtitles.

This means, you will need to install and use an external video player for closed captioning. MX Player works perfectly and can be installed in only a few minutes.

How To Install MX Player on Firestick, Fire TV, Android TV

Once installed, you can make MX your default player within the Settings Menu of the app.

For those who wish to use subtitles within CatMouse, this can be done after making a content selection.

Use the steps below to setup Subtitles within CatMouse.

Note: In the following images I am streaming Charade which is one of the Best Public Domain Movies.

1. Select your content and source option and choose Play with subtitles

2. Now make your subtitle selection (I always choose the one with the most downloads)
