Context: There is always a risk they're going to fight. It takes quite a bit of time to introduce them. We usually introduce them to the opposite sex, so they don't fight so much. Eventually, they just flirt with each other. Haha. Sometimes, we get new lions to breed them. 
Fact: My zoo will have the lion introduced to another of the opposite sex to reduce the risk of fights.
