Roga frowns at the rat things.  "I don't know," he says to Kara.  "I've heard of the things little rats can eat if properly motivated: that doesn't fill me with confidence about these big ones."  He shrugs.  "But yes, if we could lure one of those back to the beach, where we have more armed people, we could possibly kill it.  Maybe, at a thousand-to-one odds, we could even domesticate it.  See if it produces milk as well as wool."
