猎豹的身体是为了速度而制造的。普通猫只重125磅。它有一个小头,扁平的肋骨和瘦腿,以尽量减少空气阻力。坚硬的脚垫和钝的,半可伸缩的爪子可以作为夹板来帮助脚保持牵引力。长尾作为方向舵来操纵和稳定猫。猎豹的脊椎异常灵活。加上灵活的臀部和自由移动的肩胛骨,动物的骨架是一种弹簧,储存和释放能量。当猎豹向前推进时,它将所有四只爪子从地面上花费超过一半的时间。猫的步幅是一个令人难以置信的25英尺或7.6米。如此快速地运行需要大量的氧气。猎豹有大的鼻腔通道和扩大的肺和心脏,以帮助吸入空气和氧合血液。当猎豹奔跑时,它的呼吸速率从每分钟60到150次的休息率增加。这么快就有缺点。短跑会大大增加体温并耗尽身体的氧气和葡萄糖储备,因此猎豹需要在追逐后休息。猎豹在吃之前休息,因此猫面临失去竞争的风险。因为猫的身体适应速度,它是瘦的和轻量级的。与大多数掠食者相比,猎豹的下颚较弱,牙齿较小,而且它的强度不足以打架。基本上,如果捕食者威胁要猎杀猎豹或攻击它的幼崽,猎豹就必须跑。

The cheetah’s body is made for speed. Ordinary cats weigh only 125 pounds. It has a small head, flat ribs and stovepipe to minimize air resistance. Hard feet and blunt, semi-retractable claws act as splints to help the foot maintain traction. The long tail acts as a rudder to manipulate and stabilize the cat. The cheetah’s spine is extremely flexible. Coupled with flexible hips and free-moving shoulder blades, the animal’s skeleton is a spring that stores and releases energy. When the cheetah moves forward, it spends more than half of all four paws on the ground. The cat’s stride is an incredible 25 feet or 7.6 meters. Running so fast requires a lot of oxygen. Cheetahs have large nasal passages and enlarged lungs and heart to help inhale air and oxygenate blood. When the cheetah runs, its breathing rate increases from 60 to 150 beats per minute. There are shortcomings so soon. Sprinting will greatly increase body temperature and deplete the body’s oxygen and glucose reserves, so cheetahs need to rest after chasing. The cheetah rests before eating, so the cat is at risk of losing competition. Because the cat’s body adapts to speed, it is thin and lightweight. Compared to most predators, the cheetah has a weaker jaw, smaller teeth, and its strength is not enough to fight. Basically, if the predator threatens to hunt the cheetah or attack its cubs, the cheetah must run.
