You must watch this:
A Man Among Wolves, which I watched this past weekend on National Geographic. It's crazy.

Brief synopsis is that this guy raised a pack of wolf cubs for the past few years and basically spent all of his time with them apart from a couple of hours here and there. Interestingly, there's some sort of nature preserve in the UK that lets him roll around with them, feed with them, and the public watches. He didn't have any prior scientific training, but knew enough to teach his wolf cubs different kinds of howls and different wolf behavior.

One highlight is that when we first meet him, he is the alpha male in the pack so is entitled to the heart, lungs, and liver in the kills. So, since he can't digest the raw meat of these organs in the various dead animals he hauls in, he goes in beforehand and cuts out those organs, goes home and fries them up a bit, and then inserts them back in to the guts of the dead animal. Only then does he bring in the feast for the pack and he gets down in there and rips out those organs on gnaw on. You have to see this.

The other highlights is footage of him with the cubs when he first adopts them teaching them to howl. Baby wolf cubs learning to howl = ultimate in cuteness.
