Two of each kind

The text is specific about including different *kinds* of animals, not species. In my crude and unscientific terms, you only need one "cat" kind, one "dog" kind (includes wolf genome, etc.), one "bear" kind, etc. to contain the entire genetic backlog for reproducing many species.

Also, you could fit young elephants/girrafes, etc. instead of bringing their full grown adult size. That would be a smart move for saving space and still allowing for re-population.
