Mouse Raider
Cats Arena is a competitive game where points matter a lot. Also you need to get thirty points to win and earn money, and the combat is fast.
Click to start battles for free, and win points to unlock upgrades, outfits, and pets.
You click to move and target enemies, and launch attacks, which is kinda weird anyway. Their pets give you combat boosts.
Watch using pets is better then just fighting alone. You should upgrade outfits with money you earn from points to personalize your character and win.
