In the early 20th century, raccoons were poised to become the go-to model for animal experiments. They were some of the most curious and intelligent animals available, scientists believed, so that meant they were an obvious choice for comparative psychology studies. Though raccoons were the subject of several psychology experiments at the turn of the century, they didn't stick around in labs for long. Unlike rats, they were hard to breed and maintain in large numbers. They also had the pesky tendencies to chew through their cages, pickpocket researchers, and hide out in air vents. Despite one researcher's plan to breed a tamer strain of raccoon, the creature's future in the lab never took off.
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.
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."

What time of year do raccoons have their babies? Activity: Nocturnal in nature, raccoons are mostly active at nighttime. They are most active in spring, summer and fall, and will sleep in their dens for most of the winter. Reproduction: Reproduction begins in late winter. Females, or sows, usually give birth to 1-6 baby kits in April or May.
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.
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.
