为什么样猫猫喜欢钻盒子？猫狗等宠物真的会委屈得哭么

大箱子、鞋盒子以及①些盒状物体，猫就是喜欢将自己挤压到这种纸板做成的空间里。

科学家们说他们还没办法完全弄明白为何我们猫科朋友们如此钟爱盒子，不过他们对此作出了不少假设。最受欢迎的假说是当猫在追踪它们的猎物时，盒子为猫提供了安全感和庇护之处。

荷兰乌得勒支大学的兽医Claudia Vinke近期研究了家猫的压力等级。她发现比起那些周围没有盒子的陌生环境，猫能更快地适应周围有盒子的新环境，因为这些盒子能作为它们的应对机制(coping mechanism)。

盒子还能为猫提供安全的睡觉之所。猫科动物①天能睡①⑧-②⓪个小时，因此找到①个隐蔽的地方能提高它们的野外生存几率。美国防止虐待动物协会的科学顾问Stephen Zawistowski认为猫之所以喜欢盒子是因为它们是神秘的动物，它们喜欢隐藏起来。盒子对它们而言是①个安全且隐蔽的地方。

猫还想躲避别人的注意力，它们不擅长解决冲突，只好逃跑和躲藏。它们躲避的地方不仅仅是盒子而已。它们还会躲到任何封闭的地方，比如抽屉、购物袋甚至是水壶中。

Wired网站认为这可能是因为猫想保暖。相比人类而言，猫科动物能更好地忍受更高地温度。狭窄的地方能更好地隔绝热量，这也许能够解释为何猫会试着蜷缩在鞋盒中。当猫看到地板上的圆圈时也会发生同样的事情。

如果你用粉笔、绳子、胶带或者电线制造①个圆圈，那么①只猫就会进入圆圈中拒绝离开。这听起来可能不太真实，但网上有很多这样的照片。

Daniel Mills教授是英国研究动物行为的顶尖专家之①，他说如果圆圈形成了屏障的话，猫就会被这样的圆圈所吸引。矮小的屏障能给予猫安全感，因为它们能蜷缩起来。如果你带着猫去看兽医时，把它放到了它不熟悉的笼子里，而笼子里有个托盘的话，它就会窝在上面。

听起来猫大人就是不断在寻找安全感，所以作为铲屎官记得多给它①点爱，让它感觉到安全感。

Dogs and Tear Stains

Your snow-white poodle is so cute -- but he’d be even cuter without those reddish-brown streaks under his eyes. Dogeye discharge and tear staining are common problems, especially with certain breeds. So, what causes these issues, and what can you do to remedy them? WebMD offers answers to four common questions about dog eye problems and discharge.

①. What causes tear stains under a dog’s eyes?

Excessive tearing can occur as a result of irritation to your dog’s eyes or because your dog’s tears are not draining properly.

Just as your eye waters if a speck of dust blows into it, dogs’ eyes will make tears when irritated to flush away anything harmful. When the eyes are continually irritated, this can lead to chronic tearing that produces stains. Conditions that might irritate the eye include dog eye infections, glaucoma, and eyelash or eyelid problems.

In a normal dog eye, there are small holes that drain tears away from the eye and down the throat. A variety of dog eye problems can affect this drainage, causing excessively watery eyes. These conditions include:

Shallow eye sockets. If the eye sockets aren’t big or deep enough, tears can spill out onto the fur around the eyes.Eyelids that are turned inward. If the eyelids roll in toward the eyeball, the drainage holes for tears (called puncta) may become blocked.Hair growth around the eye. If hair grows too close to the eye, it can wick tears away from the eye and onto the face.Blocked tear drainage holes (puncta). Previous dog eye infections or eye damage can cause scar tissue to form that blocks some of the drainage passages for tears.②. Which types or breeds of dogs are more susceptible to dog eye discharge and tear stains?

Regardless of breed, white dogs are more likely to have visible tear staining on their faces, because the pigments in their tears can easily dye light-colored fur. Also, dogs with long hair on their faces may be more prone to excessive tearing.

Short-nosed dog breeds, such as Shih-tzu, Pekingese, Maltese, and pug, are prone to excessive tearing because they often have shallow eye sockets or hair growth in skin folds around the eyes that cause problems. Also, cocker spaniels and poodles are more likely than other breeds to have blocked tear ducts.

③. Can the dog eye problems that cause tear stains be treated?

It depends on the condition leading to excessive tearing. There is no way to stop dog eye discharge because of shallow eye sockets, so the goal in this situation is to minimize skin irritation and coat discoloration.

If your dog’s tear stains are developing because his eyes are always irritated, eliminating the source of irritation will help. This might include keeping hair near the eyes trimmed very short and treating infection or glaucoma, if present.

There are surgical options for certain eyelid or eyelash problems that can restore normal tear drainage and eliminate overflow onto the face.

④. What can I do to get rid of my dog’s tear stains?

Although those reddish-brown stains can be stubborn, there are certain remedies that may minimize their appearance. These include:

Antibiotics. The antibiotics tetracycline and tylosin are sometimes used to address tear staining, as they reduce or eliminate the likelihood that tear stains will form. There are concerns about the use of antibiotics for this purpose on an ongoing basis, however, because it could lead to the development of drug-resistant bacteria, which would be far more dangerous to your pup than a few unsightly stains.Whitening products. Swabbing the stains with hydrogen peroxide or using special grooming products designed for pet fur may help with tear stains.Regular washing of your dog’s face.
