Or that catnip really is like a drug for cats?

還有貓薄荷真的就像貓的毒品一樣嗎？

One of its volatile oils called Nepetalactone enters the cats' nasal tissue and acts like an artificial cat pheromone.

其中一種叫做荊芥內酯的揮髮油進入貓的鼻組織，就像人造的貓費洛蒙。

The sensory neurons are stimulated and ultimately trigger a behavioral and sexual response in the brain and body in around 80% of cats,

感覺神經元受到刺激並最終在大約 80% 的貓的大腦和身體中引發行為和性反應，

which must be nice, considering cats spend around 85% of their day doing absolutely nothing.

這其實蠻不錯的，畢竟貓一天中大約 85% 的時間無所事事。

Drinking, eating, defecating and even mating only take up about 4% combined.

飲水、進食、排便甚至交配加起來只佔 4% 左右的時間。

But when they are moving, they always seem to land on their feet.

但是當牠們移動時，他們感覺都是用腳著地。

This is because of something called the "Righting Reflex".

這是因為一種叫做 「翻正反射」的東西。

Not only do cats have very sensitive motion and gravity sensing abilities allowing them to determine which way is down, they also have an extremely flexible backbone and no collarbone.

貓不僅有非常靈敏的運動和重力感應能力，可以讓它們確定哪條路是向下的，它們的脊椎也非常靈活，沒有鎖骨。

By bending in the middle and using fast twitch muscle fibers, they can whip around without ever changing their net angular momentum.

透過在身體中斷彎曲並使用快肌纖維，牠們可以在不改變其淨角動量的情況下擺動。

And did you know that when a cat lifts its tail while being pet, it's really inviting you to smell its behind?

你知道嗎，當一隻貓在被撫摸的時候抬起牠的尾巴，牠其實是在邀請你去聞牠的屁股嗎？

Cats use scent to communicate and this exposes glands and pheromones holding their signature smell, a nice alternative to a hug or a handshake.

貓使用氣味進行交流，這會散發出腺體和具有牠們標誌性氣味的費洛蒙，是代替擁抱或握手的方法。

They also rub up against you to spread these pheromones.

牠們還會在你身上蹭來蹭去以傳播這些費洛蒙。

The glands on their face, tail and body, help them to claim you with their scent, while also leaving nearby cats signals about their identity, sexual availability and territory.

牠們臉上、尾巴和身體上的腺體幫助牠們用氣味來宣示擁有你，同時也留下讓附近的貓知道關於牠們的身份、可進行交配性和領地的信號。

On the other hand, cats bury their poop in an attempt to hide its smell.

另一方面，貓會把糞便埋起來，試圖隱藏牠的氣味。

This evolutionary instinct is not only to avoid attracting predators but to show that they're submissive to a dominant cat in the wild.

這種進化本能不僅是為了避免吸引捕食者，而且是為了表明牠們對野外占主導地位的貓很順從。

In the case of your house, this is your cats way of recognizing you as dominant.

以房子內的環境而言，這就是你的貓認同你占主導地位的方式。

Also in complete darkness, cats can't actually see, though they can see much better than you and I in dim light.

還有在完全黑暗中，貓實際上是看不到東西的，儘管牠們在昏暗的光線下比你我看得清楚得多。

Cats have a layer of cells behind the retina called the Tupetum Lucidum, which acts like a mirror reflecting extra light back at the retina.

貓的視網膜後面有一層細胞，稱為「脈絡膜層」，它就像一面鏡子，將多餘的光線反射回視網膜。

In near darkness, this gives their eyes a second chance to pick up more light, but without any light present, they can't see anymore than we can.

在近乎黑暗的情況下，這讓牠們的眼睛有第二次機會獲得更多的光，但是沒有任何光的情況下，牠們跟我們一樣看不到了。

And if you ever see a cat with three distinct colors, often called a Calico or Tortoiseshell cat, you can bet it's female.

如果你看過一隻具有三種不同顏色的貓，通常被稱為三色貓或玳瑁貓，很大機會是母貓。

The fur color gene is located on the "X" chromosome.

毛色基因位於 X 染色體上。

This means females can have two colors, in addition to white, because they have two "X" chromosomes.

這表示母貓除了白色之外還可以擁有兩種顏色，因為牠們有兩條 X 染色體。

The male "Y" chromosome, on the other hand, does not have any color genes.

另一方面，公貓的 Y 染色體沒有任何顏色基因。

As a result, males will generally only have one color along with white, though in rare genetic cases, it is possible for them to have more.

因此，雖然在罕見的遺傳情況下，公貓確實可能有更多顏色，但牠們通常只有一種顏色和白色。

Interestingly, we still don't really know why cats purr.

有趣的是，我們仍然不知道貓為什麼會發出呼嚕聲。

In fact, cats purr both during pleasurable situations but also while they're in duress or injured.

事實上，貓在愉悅的情況下還有受到脅迫或受傷時都會發出呼嚕聲。

While many believe it's a means to communicate passivity or pleasure,

雖然許多人認為這是傳達被動或快樂的一種方式，

one interesting theory suggests that the frequency that purrs occur at 24 - 140 Hz promotes healthy bone growth and healing.

一個有趣的理論表明，24 - 140 Hz 的呼嚕聲頻率可以促進骨骼健康的生長和癒合。

Because cats have adapted to a lifestyle with frequent rest and sleep, this may be a low energy mechanism to promote muscle and bone health.

因為貓已經適應了經常休息和睡眠的生活方式，這可能是一種促進肌肉和骨骼健康的低能量機制。
