How to Install CatMosue APK on FireStick

In this tutorial, you are going to learn how to install CatMouse on FireStick. These instructions work equally well on any Amazon Fire TV line of devices including FireStick 4K and Fire TV Cube. Moreover, the same APK file can be used for Android TV boxes. In fact, except for the interface of FireStick and Android boxes, all the steps remain the same for the installation of the app.

As I write this guide, CatMouse is a fairly new app in the streaming world. However, it has already created a lot of ripples. Considered a clone of Terrarium TV, CatMouse delivers high-quality on-demand entertainment. First, its content library is huge; there is everything you could ask for and new content is regularly added. Second, it is fetching top-quality streaming links allowing you to stream in up to 1080p resolution.

CatMouse is a lightweight app. That makes it fast. It is also quick to fetch and resolve streaming links. What I like the most is that CatMouse is completely ad-free at this time. All in all, it is one incredible option to watch your favorite content. Get 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.

Here are the reasons why you must use a VPN all the time.

CatMouse is a third-party app for FireStick because we are not getting it from Amazon Store. We are getting it from an external source. As a prerequisite, we need to enable Apps from Unknown Sources.

Here are the steps:

How to access and use CatMouse app on FireStick

If you have been using FireStick for a while, you would probably already know how to access your apps. However, if you are new to it, you may want some help with it.

All your apps can be found in the section Your Apps & Channels. This section is available in the second row on the home window of your FireStick. However, on the home window, it only displays 15 apps. If you have more apps than that, you will need to expand this section. Here is how you can do it:

– Highlight Your Apps & Channels row on the home screen of FireStick. Go all the way to the left. Click See All
– Long press the Home key on your Amazon FireStick remote. When the popup is displayed, click Apps

You may now scroll down to the bottom and click the CatMouse app icon
