It is probably illegal to keep a wild animal without permits. Use caution when handling all wildlife. Even babies can be dangerous and bite. Wild animals are very difficult to take care of and if feed the wrong thing or they are not taken care of properly they will die. Always wash your hands after handling wildlife.
Wildlife can carry diseases which can be transmitted to people.
Raising a wild animal by hand is not good for the animal. They need to be taught to survive by watching their parents. They need to learn where the food is in their habitat. If a human raises them they are never really afraid of humans and don't learn proper survival skills. Many animals raised by hand die when released into a strange wild area, they don't know how to find food, where to find food and get into fights with the native animals that live there.
