 SCP-798 resembles a healthy adult grey or beige rat. However, it has been seen to engage in behaviors usually associated with corvids or higher mammals, such as self-awareness, problem-solving, suggesting heightened intelligence. SCP-798's dietary requirements, sleep patterns, and metabolism are normal for ratus norvegicus. SCP-798 possesses the ability to influence other animals from a distance and even control them if allowed to establish physical contact. The subject's abilities have proven to be far less effective on cetaceans, corvids, and primates. Subject appears incapable of establishing a physical link with such creatures. Recent tests imply that SCP-798 demonstrates different behaviors when interacting with members of its own species.
