Back in the day, there was a game that pitted cats and dogs in a showdown, but not the usual chasedown. Instead, they are placed in different backyards and they throw different 'weapons' at each other. Fast forward to 2013, and a modern version was developed. If you are looking for decent Android games free to download, then you better check this out. 

Developed by Game Excellent, Cat vs. Dog (Cat and Dog's War) is your usual 'firing' game where you will need to consider some physics details such as the wind direction and angle of the throw. 

There are a number of 'weapons' which you can throw in order to eradicate your opponent from the face of the earth. Some of the throw bonuses include double attacks, poison gas attacks, heavy hits, stop the wind, and restore blood. 

You can also choose whether to play the single player or 2-player game where you and a friend can fire alternately at one another. 

If you are looking for a casual game that can help you pass time, then you better download Cat vs. Dog from the Play Store for free.
