If mountain lions exist in N.H., can they purr or can they roar? (Check the hyoid bone)

Did you know that the "big four" cats - lions, tigers, jaguars, cougars (aka mountain lions) - can roar but they can't purr, whereas smaller cats, from ocelots down to the cat in your lap, can purr but not roar?

I didn't either, but a terrific video on BigCatRescue.org (spotted via Boston.com's intriguing Braniac blog) provides the scoop: The secret is the hyoid bone, in the back of the throat. If it's connected one way they can roar, if it's connected another they can purr. There's considerable debate about the details, however, including uncertainty whether mid-sized to big cats can semi-purr - that is, purr only when exhaling.
