>>I never thought they were dogs, but dog-like. Now I've looked at the site, their wee faces ARE a bit cat-like, aren't they. But what cats can crunch through tibiae?

I don't think so. We get loads of nat hist progs (David Attenborough) here covering the big cats of Africa ("Big Cat Diary" et al) and you see the critters chewing away at the gristly ends of the bones but not through them. Cats have very rough tongues for rasping the last vestiges of meat, periostium, etc. from the bones. But I think they leave it to the hyenas to polish off the bones themselves.

>>Another interesting fact I found out about hyena: they have a cast-iron constitution and can ingest even anthrax and live. If you consider the rotting carcasses that they eat on the African savanah, it figures! :-)
