The relationship seems to be similar to that of us and domestic cats. Just like domestic cats these tamed lions are acting playfully and treating him like one of there own and again like domestic cats these lions could turn on him (ever had your cat randomly start going mad scratching and/or biting you or someone else?) Obviously due to these cats being LIONS if they did turn on him in the heat of one moment it could be terrible.. lets just hope they dont and the relationship continues
