According to this article, what type of cats cannot purr? 

On an extremely rare occasion, a mountain lion or a bobcat might still be spotted by a visitor in one of our county parks. Both these wild felines can make a variety of household cat sounds. Baby mountain lions (also called pumas and cougars in different parts of the country) and baby bobcats meow like household kittens. As adults, they growl, hiss and spit when they are displeased. When they are contented, they purr.

Of course a full-grown mountain lion purrs about twenty times louder than that friendly puss who sleeps most of the afternoon at the foot of your bed. Not all kinds of cats can purr. Cats that can roar -- such as tigers, jaguars and African lions -- can not purr. And cats that can purr --such as cougars, bobcats and household tabbies -- can not roar. Until recently, exactly how purring cats managed to purr was a mystery. If you try to purr continuously like a mountain lion or bobcat, you'll quickly discover its impossible for you to do.
