He is the son of Sylvester the Cat. Physically, Junior is an anthropomorphic kitten - basically a miniature version of his father, having a large head in proportion to a small body. Aside from "Goldimouse and the Three Cats", his mother is never seen nor mentioned in the Warner Bros. shorts, and the only apparent trait Junior got from his mother is his ability to speak without his father's characteristic lisp, but has a smaller lisp than Sylvester does. Junior has been noted saying that he is three and a half years old.
