"Honestly, chickens would probably be way more useful for the eggs than their meat for a number of reasons," Lea said. Not the least of which being he wasn't sure he could bring himself to kill and cook any animal he helped raise, and the same was probably true for a number of those on board. "But either way, it still wouldn't work."

"And yeah, I don't either really, but it's more that space is really at a premium on the train. It's OK as it is now, with relatively few people having pets or the like, but if everybody did, it'd get crowded really fast. That's part of why I haven't tried to get my familiar from the last world I was in." That and not everyone was into rats, even pet rats.
