This is one of the reasons they are such a challenging wildlife species for raccoon removal experts around the world who have to deal with them. They get around obstacles that baffle other wildlife species with ease which means that backyard gardens, ponds and even garbage cans around the city suffer at their hands.
Adding to this, raccoons eat pretty much everything! Ranging from trash to fruits and small animals. As far as raccoons are concerned, everything in sight is fair game and up for grabs.
So the next time you spot a raccoon washing its food, you can go ahead and bemuse the fact that it appears to be a very hygienic animal, after all, it is a fun way to view the animals. But remember the true reason behind this behavior. These nocturnal animals are extremely intelligent and require the help of professional raccoon removal when they enter your home.

In a study examining the slowly adapting nerves in the forepaws of raccoons, researchers found that wetting the skin increases the nerve responsiveness [source: Rasmusson and Turnbull ]. Think about what happens when you look through a pair of sunglasses and then quickly take them off.
When you remove them, your optical nerve responsiveness will likely increase because more light is flooding into your retinas to illuminate what you're looking at. Likewise, when raccoons perform their dunking ritual, the water on their paws could excite the nerves in their forepaws. That, in turn, gives them a more vivid tactile experience and provides precise information about what they're about to eat.
This is a beneficial trait since the raccoon's vision isn't its keenest sense. Like primates, raccoons employ a combination of sight and touch to reach out and grasp an object unless, of course, they're reaching into murky water.
However, raccoons often use both hands, rather than one, to grasp, and they exhibit little independent movement of their digits [source: Pubols, Pubols and Munger ]. One interesting difference in tactile sense between raccoons and primates is the raccoon's lack of papillary ridges. The ridges are microstructures in our skin that help us detect friction and create our fingerprints.
In the hairless areas of human skin, namely our palms and soles, the ridges are packed with Meissner corpuscles. These individual living cells serve as specialized mechanoreceptors, responding to sensations like pressure or tension. With all of these factors combined, a study observing raccoons' eating behavior concluded that while their dexterity is specialized, it isn't as much of an anomaly as the washing behavior implied at first blush [source: Pubols, Pubols and Munger ].
From a public relations standpoint, that probably isn't such a good thing for the raccoon. Previously, the rabies-carrying, food-stealing animal had the distinction of at least washing its food. Now, it looks like those sticky fingers could use a thorough rinsing.

Raccoons are incredibly smart. Some scholars even suggest that their discriminatory abilities are equal, if not superior, to those of domestic cats. In a study published in the journal Animal Cognition, researchers assessed eight captive raccoons for causal understanding. The raccoons were shown a cylinder filled with water containing a marshmallow that was too low to grasp.
Then, the researchers demonstrated that if they dropped pebbles into the cylinder, the water level would rise so that the treat was within the raccoons' grasp. Two raccoons learned how to drop stones to get the treat. A third found an even easier way: she tipped over the tube to access the marshmallow more quickly. The researchers concluded that the raccoons were "innovative in many aspects of this task. Raccoons have five toes on their front and back paws. Their forepaws are particularly dexterous and actually look and work like slender human hands.
They use their nimble finger-like toes to hold and manipulate food, as well as a range of objects, including latches, lids, jars, boxes, and doorknobs. Raccoons are mostly solitary animals. As nocturnal creatures, they rarely venture out during the daytime, and they try to stay close to their den, only traveling far enough to get what they need to eat and drink.
Females stay with their babies called kits until they are about one year old. Males may stay with the female for up to one month before breeding, then depart after the birth of their young.
Although so many animal populations have been diminished because of human urbanization and growth, raccoons have readily adapted to living alongside people.
According to the IUCN, the Northern raccoon is a species of "least concern," and its population numbers are rising. While there are no major threats to the survival of raccoons, they do face dangers. They are hunted for sport and trapped for their fur. In suburban locations and near water, raccoons are one of the more frequent victims of roadkill.
Additionally, raccoons are often hunted, trapped, and poisoned by homeowners and farmers who consider them a pest. In other human environments they are actually considered pest control, like in the San Diego Zoo , where they help manage rodent populations. After bats, raccoons are the second most frequently reported rabid wildlife species, according to the CDC. However, human rabies cases are rare in the United States.
