More recently, scientists gave the Aesop's Fable test to some raccoons. Researchers have adopted the well-known parable of a crow throwing stones into a pitcher to cause the water level to rise as a benchmark for animal intelligence. Raccoons were put in a space with a water cylinder, marshmallows floating on top, and stones strewn about it. They had to raise the water level first by dumping the stones before they could get to the sweet treats. Two of the eight raccoons imitated the action after being shown how to do it, but a third approached the issue differently and knocked the entire structure over.
Do raccoons die from rabies? Raccoons—along with foxes (red and gray), skunks, and bats—are considered a primary carrier of the rabies virus in the United States. While any warm-blooded animal can carry rabies, these are the ones we call “rabies vector species.”
Is raccoon feces harmful to humans? Raccoon droppings may carry several potentially dangerous diseases. Recently, however, raccoons have been recognized as the main host for an even more dangerous parasite called Baylisascaris procyonis. This is a disgusting roundworm that can cause extremely serious disease conditions in humans.
Can humans get raccoon roundworm? The species commonly found in raccoons is Baylisascaris procyonis. When infective eggs of this roundworm are ingested by humans, Baylisascaris larvae hatch in the intestine and travel through the organs and muscles. Infected raccoons shed millions of eggs in their feces.
Are the raccoons dangerous? Raccoons can carry several dangerous diseases including rabies. While incidents of rabid raccoons attacking humans are rare, it's not something you want to risk.Raccoons carry two other diseases, roundworm and leptospirosis, that can also be transmitted to humans and pets.
Can a raccoon drown a dog in water? Raccoons may look cute, Jagendorf says, but they're quite capable of defending themselves. Even with two dogs against a single raccoon, the tussle was a standoff. "Later an animal control officer told us that a raccoon can drown a dog in two inches [five centimeters] of water just by holding its nose under water."
If you give raccoons a problem, they'll typically figure out how to solve it as long as there's food involved. They have repeatedly demonstrated this in labs in addition to yards and campsites. Early in the 20th century, ethologist H.B. Davis presented 12 raccoons with a set of locks to pick. They had to negotiate hooks, bolts, buttons, latches, and levers to get to the rewards inside the boxes; some of the boxes had multiple locks. The raccoons eventually managed to bypass 11 of the 13 defenses.
