| 释义 |
High-rise syndrome is the phenomenon of cats falling from higher than two stories ({{convert|7|–|9|m|ft|abbr=on}}). This is generally from high-rise buildings, or skyscrapers, and is also used to refer to the injuries sustained by a cat falling from a great height. Injuries sustained by cats fallingCommon injuries sustained in cats after a fall include:
Studies done of cats that have fallen from 2 to 32 stories, and are still alive when brought to a veterinarian clinic, show that the overall survival rate is 90 percent of those treated.[2][3] [4][5]In a study performed in 1987 it was reported that cats who fall from less than six stories, and are still alive, have greater injuries than cats who fall from higher than six stories.[6][7] It has been proposed that this might happen because cats reach terminal velocity after righting themselves (see below) at about five stories, and after this point they are no longer accelerating and can no longer sense that they are falling, which causes them to relax, leading to less severe injuries than in cats who have fallen from less than six stories.[8] Another possible explanation for this phenomenon is that cats who die in falls are less likely to be brought to a veterinarian than injured cats, and thus many of the cats killed in falls from higher buildings are not reported in studies of the subject.[3] In a more recent study, it was observed that cats falling from higher places suffered more severe injuries than those experiencing shorter drops.[9] Righting{{Main|Cat righting reflex}}During a fall from a high place, a cat can reflexively twist its body and right itself using its acute sense of balance and its flexibility.[10] This is known as the cat's "righting reflex". The minimum height required for this to occur in most cats (safely) would be around {{convert|90|cm|ft|abbr=on}}. However, it has been argued that, after having reached terminal velocity, cats would orient their limbs horizontally such that their body hits the ground first.[9] A 1987 study speculated that this is done after falling five stories to ensure the cat reaches a terminal velocity by thereafter relaxing and spreading their bodies to increase drag.[3][11] Why cats fall from high placesCats have a natural fondness for heights. If a cat is distracted by potential prey, or if it falls asleep, it can fall. If this were to occur in a tree, for example, the cat would often be able to save itself by grabbing on with its claws. Many building materials such as concrete and painted metal do not allow a cat to grip successfully.[12] References1. ^{{cite web |url=http://sciencebasedlife.wordpress.com/2012/04/13/how-do-cats-survive-falls-from-great-heights/ |title=How do cats survive falls from great heights? |work=Science-Based Life |first=Kyle |last=Hill |date=April 13, 2012 | access-date=}} 2. ^{{cite journal |last=Diamond |first=Jared M. |date=April 14, 1988 |title=Why cats have nine lives |journal=Nature |volume=332 |issue=6165 |pages=586–587 |doi=10.1038/332586a0|pmid=3357516 }} 3. ^1 2 {{cite web| url = http://www.straightdope.com/classics/a5_190.html| title = Do cats always land unharmed on their feet, no matter how far they fall?| publisher=The Straight Dope| date= July 19, 1996| access-date = March 13, 2008}} 4. ^{{cite web |title=High-Rise Syndrome |url=https://www.aspca.org/pet-care/cat-care/common-cat-diseases |website=The American Society For the Prevention of Cruelty to Animals |publisher=ASPCA |access-date=27 March 2015 |date= |author=}} 5. ^{{cite journal|title=Feline high-rise syndrome: 119 cases (1998–2001)|first1=D.|last1=Vnuk|first2=B.|last2=Pirkić|first3=D.|last3=Matičić|first4=B.|last4=Radišić|first5=M.|last5=Stejskal|first6=T.|last6=Babić|first7=M.|last7=Kreszinger|first8=N.|last8=Lemo|date=October 1, 2004|publisher=|journal=Journal of Feline Medicine and Surgery|volume=6|issue=5|pages=305–312|doi=10.1016/j.jfms.2003.07.001|pmid = 15363762}} 6. ^{{cite journal |pmid=3692980 |year=1987 |last1=Whitney |first1=WO |last2=Mehlhaff |first2=CJ |last-author-amp=yes |title=High-Rise Syndrome in cats |volume=191 |issue=11 |pages=1399–403 |journal=Journal of the American Veterinary Medical Association}} 7. ^{{cite web |url=http://www.petplace.com/cats/highrise-syndrome-in-cats/page1.aspx |title=Highrise Syndrome in Cats |work=petplace.com |first=Dawn |last=Ruben |date=September 21, 2014}} 8. ^Falling Cats {{webarchive |url=https://web.archive.org/web/20070712033200/http://www.ocf.berkeley.edu/~barneye/kitty.html |date=July 12, 2007 }} 9. ^1 {{cite journal |pmid=15363762 |year=2004 |last1=Vnuk |first1=D |last2=Pirkić |first2=B |last3=Maticić |first3=D |last4=Radisić |first4=B |last5=Stejskal |first5=M |last6=Babić |first6=T |last7=Kreszinger |first7=M |last8=Lemo |first8=N |last-author-amp=yes |title=Feline High-Rise Syndrome: 119 cases (1998-2001) |volume=6 |issue=5 |pages=305–12 |doi=10.1016/j.jfms.2003.07.001 |journal=Journal of Feline Medicine and Surgery}} 10. ^{{cite web|title=Falling Cats |url=http://www.verrueckte-experimente.de/leseproben_e.html |accessdate=2005-10-24 |deadurl=yes |archiveurl=https://web.archive.org/web/20050921124243/http://www.verrueckte-experimente.de/leseproben_e.html |archivedate=September 21, 2005 }} 11. ^A 1987 study published in the Journal of the American Veterinary Medical Association of 132 cats that were brought into the New York Animal Medical Center after having fallen from buildings. 12. ^{{cite web |title=High-Rise Syndrome |url=http://www.aspca.org/pet-care/cat-care/high-rise-syndrome |website=ASPCA |access-date=30 April 2015 |date= |author=}} External links
