往年我對於貓咪戴鈴鐺這件事情,認為可能會讓貓咪因此感到焦慮,或者是鈴鐺聲聽久傷耳,所以抱持著反對立場。但在這幾年相關的研究越來越多,有些事情跟我當初想的不太一樣,所以再次重新跟大家分享一下我的看法:
1.鈴鐺究竟能不能幫助野生動物逃離貓的魔爪?
先說結論,鈴鐺有效,但有其他更安全更有效的產品(如THE CATBIB),然後家貓不要放養,乖乖待在家裡就好不要放出去亂。
相關的研究:
Equipping cats with bells seems to reduce their predation on wild birds and mammals…this practice can be recommended to owners seeking to reduce such predation. (Ruxton, G. 2002)
還有一些類似的研究:
Cats equipped with a bell returned 34% fewer mammals, and 41% fewer birds than those with a plain collar. (Nelson, S. 2005)
2.鈴鐺會造成貓咪聽覺受損或焦慮嗎?
聽覺受損的部分這點有研究,因為噪音導致聽覺功能受損的機制,這方面貓跟人很像,所以有人以貓作為實驗動物做了相關實驗,可參考:
Auditory brainstem responses predict auditory nerve fiber thresholds and frequency selectivity in hearing impaired chinchillas.
如果你懶得看,我直接說結論,答案是”不會”。
由於該研究用的是專門的聲音控制裝置,並沒有使用到鈴鐺,所以這鈴聲是我自己拿分貝計去測的,其平均音量大約是80分貝左右。這個音量要讓聽覺受損的難度,大概就像你在地上撿了一顆石頭想要丟中天上的飛機一樣,有那個可能,但微乎其微。
至於會不會讓長期繫上鈴鐺的貓咪焦慮?
關於這點沒有相關研究,僅知道貓的聽覺頻率比人更廣,音量也是人聽到的四倍(大家有空可以去科教館玩,那邊有一頂貓頭盔可以模擬貓咪聽到的音量,基本上,貓就是可以聽到超細微的聲音)。所以關於這一點,目前無法證實是否有影響,如果有,會有多大的影響?
我是認為,以人的角度能替貓設想到這件事,就是代表你重視動物福利,如果連你都不喜歡那樣的東西長期配戴在自己身上,那幹嘛還給貓戴?
倒是近期有篇比較好玩的研究,主要是在講有一些特定的聲音會引起老年貓的癲癇,可參考:
Levetiracetam in the management of feline audiogenic reflex seizures: a randomised, controlled, open-label study.(Lowrie M, et al. J Feline Med Surg. 2017.)
結論:
雖然鈴鐺沒有這麼萬惡深淵,但以風險考量下,即使是安全項圈也還是有不安全的時候,加上我實在想不到有什麼情況是非得讓貓配戴鈴鐺不可的理由。很多環境上的問題都是我們身為飼主可以努力改善的,所以我認為是不需要沒事找事做,你當你在改車啊?
《附註》
很多人在問什麼樣的聲音會引起貓的癲癇,跟大家分享一下:
The sounds that trigger seizures vary between individual cats, and a huge variety of different sounds were identified as triggers. Some of the more common trigger noises included:
*crinkling tin foil
*a metal spoon clanging in a ceramic feeding bowl
*chinking or tapping of glass
*crinkling of paper or plastic bags
*tapping on a computer keyboard or clicking of a mouse
*clinking of coins or keys
*hammering of a nail
*clicking of an owner’s tongue
至於我個人經驗裡面,這我們家阿橘曾經因為電音舞曲的吵雜聲音發作過。

tongue nerve 在 林作 Facebook 的最佳解答
My recent comments about the legal profession have clearly hit a nerve with many lawyers and sparked a debate about the future of the Bar career. Obviously, litigation will not be disappearing any time soon so there will still be a need for advocacy and legal services far into the future. So why do I say that this most learned of professions is a dying one?
Firstly, I wanted to dispel, in a tongue-in-cheek way, the widespread misconception that being a barrister is a glamoro...

リラックス出来るようにゆっくりした優しい囁き声になるようにしました。
動画撮影のこと…
家でオカメインコちゃんを飼っているのですが、
最近、発情期になり、
起きている間中ずっとビービーと鳴いているので、
なかなか録音が出来ず…
今回は、お風呂場で声を録音して、
その声に合わせて自分の部屋で動画を撮りました。
少し違和感があるかもしれません。
滑舌が悪いので、日本語字幕を付けました。
複数の字幕を付けたかったんですが、
やり方がわかりませんでした(><;)
余談ですが、
何年か前、よく自律神経訓練法をやっていました。
その頃、自己催眠にハマっていて、
始める時にリラックスさせるために自律神経訓練法を行っていましたが、
いつもその段階で寝てしましなかなか自己催眠をかける事が出来なかったのでした(笑)
■I'm sorry my translation is wrong
I tried to be a gentle whispering voice that gently relaxed so I could relax.
Movie shooting ...
I have a parakeet at home,
Recently, during the estrus period,
As I'm blowing all the while I am awake,
It is hard to record ...
This time, I recorded the voice in the bathroom,
In accordance with that voice I took a video in my room.
There may be a slight incongruity.
I have Japanese subtitles because my tongue is bad.
I wanted to add more subtitles,
I did not understand how to do it
Aside from that,
A few years ago, I was doing an autonomic nerve training method well.
At that time, I was addicted to self-hypnosis,
Although I was carrying out autonomic nerve training method to relax at the beginning,
I always fell asleep at that stage and I was not able to pretend to self-hypnotize easily (lol)

집에서 앵무새를 기르고 있는데,
최근 발정기가되어,
깨어있는 동안 내내 비비와 울고 있기 때문에,
좀처럼 녹음 못하고 ...
이번에는 목욕탕에서 소리를 녹음하여
그 소리에 맞춰 자신의 방에서 동영상을 찍었습니다.
조금 위화감이 있을지도 모릅니다.
발음 연습이 나쁘기 때문에, 일본어 자막을 넣습니다.
여러 자막을 넣기 싶었 습니다만,

몇 년 전 잘 자율 훈련법을하고있었습니다.

항상 그 단계에서 자고했습니다 좀처럼 자기 최면을 걸 수가 없었다있었습니다 (웃음)
