In this tutorial, you are going to learn how to install CatMouse APK on FireStick. These instructions work equally well on any Amazon Fire TV line of devices including Firestick Lite, FireStick 4K, FireStick Lite 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.
Update: This FireStick app is no longer reliable. See our list of the best FireStick apps for some alternatives.
Cat Mouse has been around for a while now. Initially considered a clone of Terrarium TV, CatMouse APK offers on-demand entertainment. It has a huge content library; there is everything you could ask for, and new content is regularly added.
CatMouse is part of our collection of Best Apps for Amazon FireStick.
The app usually fetches quality content but sometimes runs into issues. Therefore, to get the best results, use it with Real Debrid.
Attention, FireStick Users!
Governments and ISPs constantly monitor your online activity, and accessing copyrighted content on your Fire TV Stick could lead to serious trouble. Currently, your IP is visible to everyone. I strongly recommend getting the best FireStick VPN to mask your IP address and securely stream your favorites.
I personally use ExpressVPN, the fastest and most secure VPN available. Not only is it easy to install on any device, it comes with a risk-free 30-day money-back guarantee. Plus, if you're not 100% satisfied, you can always get a refund. ExpressVPN is currently also offering a whopping 3 extra months free on their annual plan!
