    貓總能引起人們的極大興趣。它們可以對人友好，充滿柔情。但是，它們又有自己神秘的生活方式。它們從不像狗和馬一樣變得那么順從。結(jié)果是人們已經(jīng)學(xué)會尊重貓的獨(dú)立性。在它們的一生中，大多數(shù)貓都對人存有戒心。最使我們感興趣的一件事情就是一種通俗的信念——貓有九條命。顯然，這種說法里面包含著許多真實(shí)性。貓?jiān)诘�落時(shí)能夠大難不死是有事實(shí)作為依據(jù)的。
    最近，紐約動物醫(yī)療中心對132只貓進(jìn)行了為期5個(gè)月的綜合研究。所有這些貓有一個(gè)共同的經(jīng)歷：它們都曾從高層建筑上摔下來過，但只有其中的8只貓死于震蕩或跌傷。當(dāng)然，紐約是進(jìn)行這種有趣的試驗(yàn)的一個(gè)理想的地方，因?yàn)槟抢锔�本不缺乏高樓大廈，有的是高層的窗檻從上往下墜落。有一只叫薩伯瑞的貓從32層樓上掉下來，但只摔斷一顆牙。“貓就像訓(xùn)練有素的跳傘隊(duì)員，” 一位醫(yī)生說。看起來，貓跌落的距離越長，它們就越不會傷害自己。在一個(gè)長長的跌落過程中，它們可以達(dá)到每小時(shí)60里甚至更快的速度。在高速下落中，貓有時(shí)間放松自己。它們伸展四肢，就像飛行中的松鼠一樣。這樣就加大了空氣阻力，并減少了它們著地時(shí)沖擊力帶來的震動。
