How to Install CatMouse APK on FireStick

This guide will show you how to install the CatMouse APK on FireStick and all other Fire TV Devices (Fire Stick 4K and Fire TV Cube)

CatMouse APK is certainly one happy discovery as a streaming companion for my FireStick. Let me tell you why I have started recommending this app these days. For the starters, it is the big library of movies and shows and the fact that new content is updated rather quickly. And, it is the streaming quality that keeps me hooked to this app. This app is finding healthy, working links that resolve swiftly. There are lots of 1080p, 720p and even SD links.

The app is stable and reliable. It has been designed as a clone of the now decommissioned Terrarium TV app. It resembles Terrarium TV in both form and function. CatMouse APK has now been added to our line up of Best Apps for FireStick.

The installation process of CatMouse FireStick APK will take the following course:

– Turn ON the option Apps from Unknown Sources
– Install the Downloader app on FireStick
– Download and install CatMouse APK using the Downloader app

We are now going to get started with the installation process. Here is how we do it:

Attention FireStick Users: Read before you continue

Governments and ISPs across the world monitor their users' online activities. If found streaming copyrighted content on your Fire TV Stick, you could get into serious trouble. Currently, your IP is visible to everyone. I strongly recommend you to get a good FireStick VPN and hide your identity so that your movie viewing experience doesn’t take a bad turn.

I use ExpressVPN which is the fastest and most secure VPN in the industry. It is very easy to install on any device including Amazon Fire TV Stick. Also, it comes with a 30-day money-back guarantee. If you don't like their service, you can always ask for a refund. ExpressVPN also has a special deal where you can get 3 months free and save 49% on annual plan.

Great! The CatMouse APK FireStick app is now installed. Go ahead and enjoy unlimited streaming.

Before you start streaming with your Fire Stick, there is something incredibly important you must know. All your online activities are subject to surveillance and monitoring by your ISP as well as your Government. Streaming licensed or copyrighted videos for free could land you in legal troubles. 

The good news is that you can hide all your online and streaming activities from anyone who might be watching and that includes your ISP, Government or any third-party entity. What you simply need is a reliable VPN for your FireStick. With a VPN, you can stream with complete peace of mind as it will encrypt your internet connection and keep it hidden from the prying eyes.

I am not encouraging you to stream content illegally. I do not condone such activities. However, your privacy matters and it must be maintained. What if you do not intend to stream copyrighted content and still end up doing it anyway? You would not want to be penalized for an unintentional mistake. 

I have been using ExpressVPN for a long while and confidently recommend it as the best, fastest and safest VPN for FireStick.

Let me show you how to start using a VPN on FireStick under 2-minute.

#1. Subscribe to ExpressVPN: Click HERE to subscribe to ExpressVPN. You can save up to 49% on the annual plan. ExpressVPN also offers a 30-Day full refund guarantee in the event you are not satisfied with it. However, if you intend to use a VPN, I don’t see any reason why you would want to opt out of it.

#2. Look up for ExpressVPN on FireStick: You can download ExpressVPN from Amazon Store. From the home-screen of your FireStick, select the Search function (top-left) and look up for ExpressVPN.

How to use CatMouse APK on Amazon FireStick

When you go to the home screen after installing any app, you don’t find the app there. Any newly installed app is not going to appear on the home screen unless you have 15 or fewer installed apps on FireStick.

You may access any app from Your Apps & Channels and also move it to the home screen. Let me show you how:

– Go to the FireStick home screen

Select the second row from the top named Your Apps & Channels

Now, use the left navigation key and go as far on the left as you can

Click See All

– This is the list of all your official and third-party apps you have installed. Navigate to the bottom of this list and select CatMouse APK to open it

set up catmouse apk on Firestick

– If you would rather have it on the home screen, use the menu button on the remote

Click Move in the bottom-right

Drag and release the CatMouse APK in any of the three rows on the top

You will now see the CatMouse APK on the home screen of FireStick in the Your Apps & Channels row

Our link is usually up to date with the latest version of the app. However, in case we missed, you may see the update prompt like you see in the following image. I suggest you update the app if it lets you by clicking the Update button

Dismiss any disclaimers or prompts by choosing the appropriate options

The CatMouse APK will also ask you to choose the default video player. The default choice is the built-in ExoPlayer.

However, I prefer the MX Player. It is faster and more stable.

If you think you didn’t make the right player choice here, don’t worry. You may choose the preferred player later in the CatMouse app Settings

When the main screen of the CatMouse APK finally loads, it looks like this. TV Shows are displayed by default.

The app has been coded to feature the trending and latest titles first. If you are looking for something else, there are a few ways to search, filter or sort the content:

– Click the Search option (lens image) near the top-right corner to look up for any specific title manually
– Click the striped triangle in the top-right corner to filter content by year
– Click the tiny triangle to sort titles category-wise (Recently Updated, New Shows, Premieres, Airing Today, Most Popular, Most Played, etc.)

Let us now explore the menu options and Settings

As you can see, the menu button is on the far left on the top (3 lines). The menu option lets switch between TV Shows and Movies. It also has the Favorites section from where you can access all the episodes or movie titles you have marked as favorite.

You also access CatMouse FireStick app Settings from here

You will find a range of options here. You may never use most of them. Here are some of the most commonly used options:
– Clear Cache (to fix buffering issues)
– Choose default video player…
Real Debrid authorization (not shown in the image below)
– Trakt authorization (not shown in the image below)

I guess that is pretty much it. You may start streaming now.

Winding Up

CatMouse has emerged as a wonderful streaming option for those who are looking for a quality APK for FireStick. The app has a massive media library. That’s not something uncommon. All our featured FireStick APKs offer the same content collection.

What impresses me the most about CatMouse APK on FireStick is its ability to pull the finest streaming links from the top sources on the web. I have been able to find several working 1080p links for a lot of movie titles and episodes. I am glad I found this app and I am happy to share it with you now.
