Why do animals in nature don't have to wipe their bottoms, but humans do?

Wiping your ass with paper is a kind of cleaning behavior invented by people. Other animals also have ways to clean their hair and buttocks, and some animals don't even need them at all. There is no denying that when it comes to defecation, people really can't do without cleaning up after each time, because no animal has ever hated its own excrement like people. Other animals will even get close to their own feces, haha. Let's talk about this topic.

Herbivores hardly need to wipe their bottoms, and there is basically no concern in this regard. First of all, it doesn't mean that other animals don't wipe their bottoms, because most animals in nature are herbivores. Herbivores consume a lot of fiber, and feces generally form dung balls, which are relatively dry. For example: sheep dung balls! Dung balls will slowly flow out of animals' anus, just like pebbles, and rarely stick to other places. But herbivores occasionally get sick and have diarrhea. It will also stain the fur and irritate the ass. But the advantage is that the muscles of other animals' buttocks are on the outside, and the anus is completely open, which is easy to dry and difficult to breed bacteria. Tail, running can clean up sticky feces. Generally speaking, herbivores don't get sick, so there is no need to wipe their bottoms at all.

Carnivores are usually clean, but there are exceptions. It is also necessary to clean up the feces of carnivores, which are much thicker, watery and delicious than those of vegetarians. That's why we can run around in the fields full of sheep droppings and balls, with almost no influence, but except for the droppings of large herbivores, it's too big after all. Carnivores often eat the fur and muscles of their prey and comb their hair to make up for the lack of fiber. This helps to form stools, because the stools formed by a diet rich in protein are often shapeless, watery and thick.

Although the anus of carnivores is also exposed, it will remain dry and hygienic most of the time, but the sanitary situation after defecation is worse than that of herbivores, which is prone to sanitary problems and bacterial infections. If there is too much feces attached to the anus, bacteria will breed, buttocks will be stimulated, and carnivores also have their own cleaning methods. Cat owners should often see cats licking gracefully with their legs behind their necks, and dogs and cats do the same.

Others think that dogs are cleaning up their own feces by rubbing their bottoms on the ground? However, this behavior is more than just cleaning up your ass. Dogs have anal glands in their buttocks, which can secrete foul-smelling secretions. These secretions can help the dog mark his territory, and also play a role in lubricating the anus when the dog defecates, so that the dog can defecate smoothly. Sometimes, these secretions will turn into black or dark brown liquid or mud for a long time, which will irritate the dog's buttocks. That's why dogs rub around on the ground, trying to relieve this stimulation, and dogs lick their own ass. And the anal glands of dogs are likely to be infected. Anyway, it's itchy and uncomfortable. Another reason may be caused by tapeworms. So your dog is rubbing the ground, so the shovel officer should pay attention. This is not wiping his ass.

People: No matter from diet or body structure, every meal should be cleaned up before talking about people! Man is an omnivore, born to fly, run on the ground and swim in the water. Anything that can be put on the table is welcome. So our feces are worse than carnivores. Most of us often eat high-protein and high-carbohydrate foods, which means that our excrement itself is easy to stick everywhere. However, some people prefer to eat coarse grains and vegetables, so there will be no need to stick to the anus and wipe their ass after defecation! Come to think of it, you should have had such a situation.

The last reason is the problem of human body structure. We are bipedal animals, with developed hips and internal measurement of muscles, and encroached on the active parts of anus. Just like playing basketball in a narrow alley, you will always hit a wall. Quadrupeds have different muscle directions, and the muscles are on the side, which provides a large area for anal activity and rarely hits the wall.

But we can get around this anatomical obstacle by squatting down. When we squat, the gluteus muscles will be taken to the outside to provide a place for anal operation. But considering the quality problem of our feces (containing a lot of water) and our anus is often in a closed environment, we still hate our feces. What shall we do? We can only be obedient and then wipe our ass.

So, if you don't want to wipe your ass, eat more vegetables, squat down as much as possible, relax your hip muscles and make way for Mr. Anal!
