Reported by deleted account:

Finding animals is a quick and (too) easy way to get food. They just stand there waiting to be killed.

Would it be possible to make animals act more like "wild" animals, perhaps run away from players? I think their AI has this behaviour already. They run away if you hurt them. Perhaps this could be triggered through a plugin when a player is close. This would add a whole new aspect of survival and I think this would fit this plugin well.

What do you think, Diemex?

Similar to #9.

Possible to "tame" such animals? (I'm assuming there's some sort of "living time" that PopulationDensity uses, so I'll investigate that.)

I'm gonna bump this because i'd LOVE to have this on my server
I agree, animals are way too easy to hunt, which is not realistic at all!
Its a great idea to have them run away when you are near, like the rabbits!

In 1.9 it seems rabbits exhibit this behavior?
