Which animal

[coget]

Hi,
There was a documentary a couple of years ago about an animal that has to constantly hunt and eat to survive, I'm sure it was a mammal of some kind about the size of a cat. Any ideas?

The pygmy Shrew needs to feed every couple of hours, or so.

Possibly a wolverine - http://en.wikipedia.org/wiki/Wolverine -
also known as a glutton, which may be a clue.
