Animal Behaviors Making You Feel Warm 动物的这些行为让你感到很暖心
If you ever feel a little bit under the weather， the Internet will help with videos about adorable cats and other fluffs. You could possibly brighten up your day.
We are here to warm up your hearts with some behaviors of animals.
Cats don’t think of us as humans. Instead， they see us as equals， just like other cats.
By nudging you with their heads they’re actually greeting you as they would greet another member of their cat family. This means that to them humans are probably the ugliest， biggest， and clumsiest cats they’ve ever seen but they accept humans into their family and love humans anyway.
Your dog actually loves you， not just because you give them food and walks.
Studies that measured oxytocin levels， heart rates， and other biometrics showed that levels of bonding hormones rose and heart rates fell in both humans and their dogs after interacting with each other.
In other words， when you pet your dog， both of you produce more of the same hormone， and both of you relax more.
Cows have “best friends” and are happier when they’re with them.
A study from Northampton University found that when cows were paired with another cow that shared a social bond with them， their heart rate was lower and they were more relaxed while they were penned.
Hundreds of trees become seedlings every year because of some squirrels who forgot where they buried their food.
According to Rob Swihart， a professor of wildlife science at Purdue University， gray squirrels bury their food （nuts， acorns， etc.） all over the place but often forget to dig them back up. Those buried seeds have a good chance of becoming full-grown trees.
When a baby elephant is born， other mothers in the social group will trumpet to celebrate or announce the baby’s arrival.
Elephants tend to stay in close “family” groups for their whole lives， which are generally made up of female elephants （the males often leave the group to mate）. So female elephants are often present for new births.
Dolphin mothers sing to their babies while they’re in the womb.
According to a study at the University of Southern Mississippi， dolphin mothers will make a “signature whistle” for the benefit of their calf while it’s in the womb. This whistle is thought to act as a sort of “name” for the mother， allowing the calf and mother to locate each other easily once it’s born. After the calf is born， other nearby adult dolphins will whistle less， likely to help the calf learn and use the right whistle.
Some fish can recognize their owner’s face.
People have a misconception that fish can’t see out of the glass of their aquariums， but the reality is that they have surprisingly good eyesight. They also tend to have different personalities. For example， some fish like to be petted.
Seahorses get “married”.
Seahorses tend to be monogamous and will intertwine their tails to stick together while floating through the ocean. Is it because they’re loving， or is it just an evolutionary aspect of their species？
The truth is， seahorses are pretty bad swimmers and spend a lot of time hiding from predators. Finding a mate for life boosts their chances of successful reproduction.
