separation of Shadowfax and Gandalf

[tinewelt]

Just a little thought... not a very hot topic for debate, but I was pondering the parting of the fellowship. In the "white rider" gandalf states

far let us ride now together, and part not in this world again

At the parting,(havens) shadowfax is present. Which leads me to assume that he also took the ship to valinor with gandalf, because it does not state otherwise. That also seems like a topic that Tolkien would have addressed if it had happened. Also, what (if any) is the signifigance of animals in Valinor? I am sure that they are present, but i have never really covered any material that gives clear understanding. Also, I wonder what the lifespan was for horses, especially the mearas Any help?
