Guinea pig! I don't know how humans look to guinea pigs, but guinea pigs look nothing like hamsters to humans. In fact, I was in South America and they served up a guinea pig to me; it's called Cuy over there, and I couldn't eat it because it looked like the animal, only cooked. I asked them to chop it up and serve it to me without the head and legs on it. It was good. I ate all of his memories and knew who the killer was.
