CatsVsDogs.io is a great IO game focusing on a brutal combat between cats and dogs. You need to select your favorite side, which is becoming a cat or a dog, then enter the fight to kill your enemies. You are supposed to eat food to increase your size as you try to vanquish a realm for your kind. Make a good use of your swinging claws to beat the rivals, let your creatures shoot at the other side, gain a lot of gold, then use them to buy new claws, collars or more medical perks. Try to claw your way up to the top spot on the leaderboard for the dominance!
