I think I mentioned this in another thread, but 'The Builders' by Daniel Polansky was pretty good. Similar to Redwall in that it is about those kind/size of animals. It has cursing, killing, blood, death, and is pretty dark throughout, but I enjoyed it.
OK, non-animal related time:
I just read a series of books by S. Thomas Russel, which centers around a British Navy Captain in the early years of the French Revolution. He is half French, which provides some good opportunities for interesting situations.
That's all I can think of for now.
20,000 Leagues Under the Sea. Read that. Repeat. Repeat. Repeat. Repeat...
