I hate seeing Hyenas get it. Lions are the real scavengers, if you're talking about kill ratios. I plan on going to the Ngorogoro Crater one day to watch the hyena burrows. A lot of people think they're disgusting, I don't however. They're one of nature's most perfect design. They've got one of the strongest jaws/body size (apart from the dreaded Gator Bear, heh-heh). Their necks and front legs are long so they can use their own leverage to carry oversized kill back to mud pits to store food for later. They eat the ENTIRE animal. Bones and all. Everything. They even eat the diseased animals without endangering their own health. Perfect. The only drawbacks are the problems they have giving birth. Spotted Hyena (as shown in Deep's video link) are the most aggressive type of hyena. There're also brown and striped hyenas, which are much more docile and eat smaller prey, such as birds, lizards, eggs, and plants. They're also a bit more handsome than the rudimentary Crocuta Crocuta (Spotted Hyena).
It has been my dream as a teenager to have a pet Spotted Hyena, like Hans Kruuk a hyena researcher in the sixties and seventies and on. He raised a cub, named Solomon, that turned out to be better than any dog he imagined. Only drawbacks. They're loud (hunting calls can be heard miles away), and they do eat an average of 6 lbs of meat per day. On the other hand, they do have one latrine area, and shell out tiny, little white chalky pellets. They use just about every nutrient available to them. Cool animals. Better than a lion by far. What does a lioness do? Sleep, then hunt for the pride lion's benefits. Lazy. A Spotted hyena can track an animal for days upon days without slowing his pace. Marvelous sense of smell, too.
I'll shut up now. You know who I'm rooting for already.
