The interesting thing about animal vision is that it's not only different in terms of black and white vision vs. color (indeed, a lot of animals that we assumed could only see in black and white, such as cats, can, it turns out, see color). Many animals have different -ways- of seeing -- for example, they may be more sensative to motion than we are, or they may be more capable of discerning details out of their peripheral vision. They may be better at tracking at a distance, or they may have a very hard time seeing things that are sitting still.

It would be interesting to do some in-depth research about the way that a certain animal senses the world and attempt to write from their perspective, but I wouldn't want to do it without a lot of research behind me, I don't think.
