Unlikely Friendhips

The San Diego Zoo has four pairs of Cheetahs and dogs who live together. Why? Cheetahs hate each other. They're like sorority girls who look alike but they actually detest one another's company. Sitll, the cheetah's need some company. So when the cheetah is about 3 months old they pair it up with a dog that is about 6 months old, so that the dog is the alpha in the relationship. Within about a week they are inseparable.
