Cheetahs can run extremely fast. In fact, cheetahs are the fastest land animal with an ability to run up to 75 miles per hour (120km/hour). Did you know they can even go from 0 to 60 in under 3 seconds! Cheetahs have what is called “semi-retractable” claws which allows them to grip at high speeds which give them extra speed as well as agility in movement during high speed chases.
Another reason why cheetahs can run so fast is because they have large nostrils which allow more oxygen to be breathed in. They also have enlarged lungs and hearts to utilize the oxygen efficiently. Last, the cheetahs tail enabls it to steer itself at high speeds making sharp turns without tumbling of falling.
Interesting Cheetah Fact: Most big cats purr upon exhaling and can roar upon exhale as well. Cheetahs, however, purr as they inhale and do not roar.
