Raccoons are strong, agile, adaptable, and they are very common in urban areas. They commonly break into garbage cans, dumpsters, steal pet food, or even enter homes via pet doors. They are great climbers, and they commonly enter attics of homes. They will rip open a hole and set up a denning area, and raise a litter of babies. They can cause a great deal of damage, and spread diseases with their feces, so removal is usually recommended.
