List of Peanuts characters
World War II ("The Cat Next Door")

A never-seen cat lives next door to Charlie Brown and Snoopy. The main focus on this cat occurred during the 1970s, although Charlie Brown referred to "the cat next door" as early as November 23, 1958. Snoopy often taunts this cat (usually starting with, "Hey, stupid cat!"), who generally responds by violently carving up his doghouse in a single swipe. They often have fights, with Snoopy generally coming worse off. The neighbors who own the cat have complained to Charlie Brown about Snoopy harassing their "kitten". The cat's name was revealed to be " World War II " in the October 20, 1976 strip.
