Pick it up, and place it back in the nest. The mother will continue to care for it, and she will do a much better job than a human can. Although you may never see the female, she returns, periodically, to care for them. Contrary to popular belief, wild animals do not make good pets. They demand an enormous amount of attention and are not as easily cared for as a dog or cat.
Most wild animals are nocturnal, sleeping during the day and active at night.
This nighttime activity can result in damaged property and an overall nuisance. Wildlife, such as raccoons, can quickly change from playful pets to harmful animals. Every year, people are injured by captive wild animals. Even if the intent is to set the animals free when they are older, people should still refrain from raising wildlife. Domesticating a wild animal will cause the animal to lose its natural fear of man.
