Thank you for your comment @edencourage.
I know of the existence of this movie, and it's one on my to watch list but it hasn't come to that. In real life meerkats have quite a defense system with always one overseeing the environment from a higher place when the group is out in the open in combination with a series of calls for different types of danger (from the sky or from land for instance). This is what i remember from some nature shows with meerkats in them.
Nice view in this movie on that fear is not something in your genes but that it comes from experiences in life.
Thank you on your view on me about animals, indeed all are needed for an ecosystem (even the spiders :D). I always been a fan of animal photography, find animals such great models with sometimes human like facial expressions, and this has grown since i got a workshop animal photography from my girlfriend. So keep an eye out here, more animal shots will follow here.

Cheers!
