Animals in the Tain

I find it interesting that this whole war seems to be fought over a bull and from reading the course documents, powerpoints, and such that many of the gods and goddesses, especially the goddesses, are zoomorphic, yet unlike The Iliad or The Mahabharata the warriors are not described with animalistic qualities. The warriors in The Tain are described by their appearance and robes. I find it odd that in a myth that seems more naturalistic and animalistic, the warrior descriptions are much more human rather than fierce. Some of the acts that are committed are horrible and atrocious, but the warriors are not compared to animals, it is simply a fact of the matter. I guess that's not really a question so much as an observation, but I was wondering if anyone else noticed this or thought anything of it?
