Looshkin is depicted as a mentally disturbed cat who has a blue pelt. He has large, sharply pointed ears that look like party hats. He is a bipedal creature with opposable thumbs that make him able to pick up objects, much to the displeasure of others. His activities usually consist of senseless babblings and innumerable sadistic acts on people, chiefly his housemate Bear, or whoever is closest when he gets his hands on a likely weapon. He is a humorous character (in the sense of black humor) by some of the things he says or the original comical scenes he'll inflict, such as pretending to be a "Gangsta" and speaking fluent slang that he picked up from "Hood Movies" and going by the name LZ. He is maniacal and merciless, and most readers assume that the reason for that is that he has a mental disorder. Karl, Looshkin's hapless bachelor owner, thinks Looshkin is just lonely and needs a female cat to play with, but the traumatized Bear vehemently disagrees.
