When the fellowship is traveling through Moria, some of them become afraid. When Aragorn sees this, he gives a big speech telling them not to be afraid. At the end of this speech, he tells the company that Gandalf can find a path better than the cats of Queen Beruthiel. My question is: What are these cats?
[Gandalf] is surer of finding the way home in a blind night than the cats of Queen Beruthiel. (Aragorn, Fellowship of the Ring)
