Yeah, but Chris is Chris so I am sure he would find some way to be unhappy and ruin it for himself and the locals.
Not necessarily. Chris hasn't done anything heinous recently that we know of.
Put it this way: if a lion is hungry for something like food or companionship, well he's going to go out hunting and seek a pride for himself isn't he?
But once he finds that pride and a mate (or multiple) and his pride of lionesses are there to do the hunting for him and keep him company, well, the only thing left for him to do is laze about and occasionally patrol his territory. Sex probably isn't an issue, either.
If one lioness is not willing and he can't force himself on her, that doesn't mean another lioness can't be convinced in some way or another.
Border patrol might not even be an issue if someone else is there to do it for him.
So why would the lion bother with going out and causing trouble for others when he has everything he needs? New territory? Mates? Food? Entertainment?
Your ferocious lion is now an overweight tabby cat lounging on the couch occasionally spying the sparrows outside but can't be fucked to do anything he doesn't absolutely have to.
Even if he wanted to. Or, if his owners allow him.
