Ds is absolutely obsessed with wildlife, particularly the "red in tooth and claw" bit. We have to spent most waking minutes pretending to be lions bringing down a wildebeest or equivalent - recently I was required to assume the role of dead buffalo in the playground so that he could be a vulture eating me. He loves David Attenborough and Deadly 60 but will only watch them if "they have eating in them".
Last night there was a documentary on Channel 4 about a hippo carcass and all the things that came and ate it, and then how it decomposed. This is exactly the kind of thing that ds would love, so we recorded it. It was on quite late so I watched about 10min last night to check how gory it was. It is very very graphic (think intestine contents spewing over hyena's face as they tuck in, decomposing carcass etc). Ds is quite happy in the knowledge that some animals eat other animals, knows about insects and bacteria that decompose dead animals etc, but has certainly never been confronted with it in such an unadulterated way. I have been surrounded by animal killing games for so long I think I have lost perspective - are we mad to contemplate letting him watch this?
