This gray and white rodent with very recognizable patterns is a nocturnal animal that sneaks into buildings using its sharp claws and climbing skills. Measuring between 50 centimeters and 1 meter on average, the raccoon is an omnivore (with a preference for worms, larvae, and other invertebrates) that can be easily tamed. Be careful, however, as this harmful mammal carries several serious diseases, including distemper and rabies.
