Cats have evolved as the "predatory hunting animal" equipped with great agility and keen senses. From almost the very start - a kitten of all species of cat shows instinctive behavior typical of hunters. Cats are extremely alert to sounds and movements. They stalk, ambush, and convert rigid stillness into rapid movements to pounce on their prey. All cats including your own domestic companion demonstrate the typical biting and clawing actions needed to bring down and kill prey quickly.
The domestic cat has the anatomical features and senses of the big cat.
bullet Lions and tigers don't purr like little cats because the smaller cat's larynx is attached to the skull by a hyoid bone which allows the little cat to purr. The lion or tiger's larynx is attached to the skull by cartilage which is flexible thereby making the lion roar. A big cat, the puma - purrs just like a domestic cat. Except, the puma sounds like a freight train instead of a little purr.
