養貓的人會發現在貓睡覺的時候,和人親密互動的時候會發出呼嚕呼嚕(cat purr)的聲音,聽起來非常治癒。這是貓咪睡著了在打鼾嗎?
很多時候貓發出呼嚕呼嚕聲因為它覺得開心愉悅,和人待在一起很放鬆。
但除此之外,貓發出呼嚕聲還有其他的原因。
Research suggests that cats can purr for various reasons, using the soft rumble as a way of communicating and as a form of self-soothing or even healing.
研究表明,貓發出呼嚕聲有多種原因,它們用這種輕柔的聲音交流或者用來自我療愈,甚至療傷。
Kittens are born blind and deaf, remaining so until they are around two weeks old. However, they begin purring after just a few days, primarily to let their mothers know where they are, and to attract their attention at feeding time.
小貓出生時看不見也聽不到,這種狀態要持續大約兩週時間。然而它們出生幾天後就會開始發出呼嚕聲,這主要是為了讓母貓知道它們在哪裡,並在餵食時引起母貓的注意。
這種透過呼嚕聲交流的方式對於養貓的人應該並不陌生,因為它們餓了想要吃東西的時候,也會發出呼嚕呼嚕的聲音來和自己的主人交流。
這種交流的呼嚕聲還會因貓咪的需求而發生變化,《新科學人》(New Scientist)雜誌就寫道:
A 2009 study found that cats can conceal a cry within their purr that triggers a nurturing instinct in their owners, similar to the cries of a human baby. The study observed that when purring to solicit food, the noise cats made was “more urgent and less pleasant”, suggesting they can manipulate their purrs to communicate different things.
2009年的一項研究發現,貓可以在呼嚕聲中隱藏一種哭喊聲,類似於人類嬰兒的哭聲,從而激發主人的養育本能。該研究觀察到,當貓發出呼嚕聲以求食物時,聲音“更緊迫,不愉快”,這表明它們可以控制自己的呼嚕聲傳達不同的資訊。
至於貓咪呼嚕聲的療愈功能就更加神奇了。
貓的呼嚕聲是貓在呼吸時喉嚨周圍的肌肉交替收縮和放鬆時所發出的聲響。這種呼嚕的頻率對於緩解疼痛和骨修復很有幫助。
Cats often purr while under duress, such as during a visit to the veterinarian or when recovering from injury.
貓經常在受到脅迫時發出呼嚕聲,例如在看獸醫或受傷恢復時。
就像人類在緊張痛苦的時候透過哭叫、大笑或者收拾自己的桌子來轉移注意力,以達到療愈的效果,貓咪透過這種呼嚕聲來讓自己平靜下來,畢竟收拾好心情才能面對獸醫呢。
也難怪美劇《生活大爆炸》中謝爾頓生病時就會讓別人唱“Soft Kitty”給他聽:
“Soft kitty, warm kitty, little ball of fur! Happy kitty, sleepy kitty, purr purr purr!”
貓咪的purr purr聲真的很治癒呢!
而呼嚕聲修復組織(tissue regeneration)的功能除了幫助貓咪自身療傷,讓其擁有“九條命”,對於人類也大有裨益。
Cats purr during both inhalation and exhalation with a consistent pattern and frequency between 25 and 150 Hertz. Various investigators have shown that sound frequencies in this range can improve bone density and promote healing.
In fact, purr-like vibration devices have been patented for potential use in therapy, and some researchers have proposed strapping vibrating plates to astronauts' feet during long space flights to retain bone density.
事實上,類似呼嚕聲的振動裝置已獲得專利,可用於一些治療。一些研究人員建議在長途太空飛行中將振動板綁在宇航員的腳上以保持其骨密度。
知道貓咪打呼嚕背後的原因以後,鏟屎官們現在是不是更瞭解自己的小主子了呢?當它呼嚕呼嚕的時候,記得具體情況具體分析,更好地瞭解貓咪的需求哦!
