This tutorial will teach you how to put CatMouse APK on FireStick. All of the Amazon Fire TV devices, like the Firestick Lite, FireStick 4K, FireStick Lite, and Fire TV Cube, can follow these steps. Also, you can use the same APK file for Android TV boxes. In fact, installing the app is the same for both FireStick and Android boxes, except for the interface.

Update: You can no longer trust this FireStick app. Check out our list of the best FireStick apps to see what else you can do.

Cat Mouse has been around a long time. At first, CatMouse APK was thought to be a copy of Terrarium TV. It lets you watch videos whenever you want. It has a huge library of content. It has everything you could want, and new content is added all the time.

CatMouse is one of the Best Apps for Amazon FireStick that we have chosen.

Most of the time, the app gets good content, but sometimes it has problems. So, you should use it with Real Debrid to get the best results.

How to Put CatMouse APK on FireStick

We will install the CatMouse app on FireStick by using the Downloader app. In Part 1, we’ll do that first.

Part 1: Put the Downloader app on your phone

You should get the Downloader app as your first step. The Amazon Store is where it is kept.

Note: We have a guide on how to sideload apps on FireStick if you need more information.

1. Go to the Fire Stick’s home screen. In the middle bar, click Find.

Note: If you still have the old version of the FireStick interface, click the lens icon in the top left corner.

2. Click Search now.

3. Look for the Downloader app and follow the instructions on the screen to install it.

Part 2: Allow apps from sources you don’t know about

CatMouse is not from Amazon Store, so it is a third-party app for FireStick. It comes from somewhere outside of us. We need to turn on Apps from Unknown Sources before we can use Downloader.

Here’s how to do it:

1. First, turn on the FireStick. Go to the menu bar on the home screen and click Settings (the gear icon)

2. When you see the following list of menu items, go to the right and click My Fire TV.

3. Open Developer Options.

4. Click Install Unknown Apps now.

5. Make sure the Downloader app is ON.

Now we’re ready to put Cat Mouse APK on FireStick.

Part 3: How to install CatMouse on FireStick

Here’s how to put this app on your phone:

1. Start the Downloader program

This is how the app’s main window looks. As you can see, there is a text field on the right where you are asked to enter the URL. When you click inside this box,

2. This on-screen keyboard now appears. Type the following URL into it:


You can just type in the shorter URL:

Update: CatMouse is not the best way to watch movies and TV shows these days. Please try one of the other apps on our list of the Best Apps for Amazon Fire TV Stick.

Click GO

3. Now we wait for the APK files to be downloaded by the Downloader app. Not much time will pass.

4. The CatMouse APK will run automatically on FireStick as soon as Downloader puts it there. When the following message comes up, go ahead and click Install.

5. We’re back to waiting for the installation to be done. Less than a minute should be enough time.

6. The app is set up when the message “App installed” appears. You could click Open to run the CatMouse app on FireStick, but I’d suggest you click DONE for now. We’ll look at the app together in a bit.

7. Click “Delete” to get rid of the CatMouse APK. You no longer need it, so you can get rid of it and make some room.

8. Click “Delete” once more

Great! You have put CatMouse APK on Amazon FireStick successfully. Enjoy!

So, before you start streaming on your Fire Stick or Fire TV, let’s look at how to use ExpressVPN to keep other people from seeing what you’re doing.

Step 1: CLICK HERE to sign up for ExpressVPN. You can get your money back in 30 days. That is, you can use it for free for the first 30 days, and if you’re not happy with how it works (which is very unlikely), you can get your money back in full.

Step 2: Turn on your Fire TV Stick, then go to Find, then Search.

Step 3: Now, type “Expressvpn” (without the quotes) into the search bar and choose ExpressVPN from the list of results.

Step 4: Click Download to put the ExpressVPN app on your Fire TV/Stick.

Step 5: Open the app and enter the login information you made when you signed up for ExpressVPN. Click Sign in.

How to get the Cat Mouse app on FireStick and use it

If you’ve used FireStick for a while, you might already know how to get to your apps. But if you have never done it before, you might need some help.

Press the Home button on your FireStick remote for a long time. When the window pops up, click Apps.


Click the three dots on the FireStick’s menu bar in the middle of the home screen.

Scroll down to the bottom and click the CatMouse app icon.

If you want to use it quickly, you can move it to the home window. Press the button with three horizontal lines on it that says Menu. Click Move on the TV pop-up (bottom right). Drag CatMouse APK to one of the three rows at the top and drop it there.

Now, let’s look at the app.

The CatMouse FireStick app needs to be able to do some things. So, when you open it for the first time, it asks you for permission. Click “Allow” to begin.

The app may tell you to download a new version if there is one. You can keep going even if you don’t update, but I suggest you get the most recent version. So, go to Update.

Throw out any prompt you see next.

You are now asked to choose the video player that will be used by default. I’d say choose MX Player. How to install MX Player on FireStick is covered in a separate guide.

You can change the default player later in the Settings.

Click the “Welcome” button to move on.

You are finally on the app’s home screen. Here is how it looks like:

By default, the main window of the Cat Mouse FireStick app will show TV Shows. You can change it in Settings if you want to.

Now, let’s click the small upside-down triangle at the top to see the list of categories (image below). There are also similar categories for movies.

You can also use the filter for the year. Click the striped triangle that is upside down in the top right corner.

You can also find the icon with three horizontal lines in the top-left corner of this app’s home screen. For the main menu, that’s it. When you click it, the menu will appear.

In the picture above, you can see the TV Shows, Movies, Favorites, Downloads, TV Calendar, and Settings menu items.

So, the Menu dropdown lets you switch between Movies and TV Shows.

Let’s open the Settings window by clicking Settings in the menu:

In Settings, you can choose from a number of options. Most of them are easy to understand. There are a lot of things you might never even need.

You can also sign in to your Real Debrid and Trakt accounts from the Settings window.

You should now be able to start using the app. If you need help with something, in particular, feel free to tell us in the comments section below.
