Ironically, Roy Anthony's post (above) validates the truth of his pseudonym.  What he chooses to overlook is that the bears evolved here.  The cats didn't.  The bears are native wild animals.  The cats are highly destructive, invasive domesticated animals placed here by human agency.  Another bit of wisdom from Mr. Heinlein:

"It's long been known that one horse is faster than another.  But which one?  Differences are crucial."
