My strategy was to start with grass and trees and then start to add hares and zebras one by one so that it would bump my score up 2 by 2. But since i am a cheetah there are very few predators. Most of the time the person playing me would ve my pray so whatever they ate i would eat to.when every so often they turn out to be my predator i avoid anything that would bump their score up and i would slowly add animals  and if i find my self losing i use the wild card.
