She incorporated a giant champagne glass into her act, similar to such as Lili St. Cyr had used, accompanied by the Bobby Darin hit "Splish Splash." She appeared as a guest on "The Dating Game," one of a number of game shows that Chuck Barris produced. During the 1980s, Natividad began appearing in pornographic productions, initially limiting her performances to appearing topless. Eventually, however, she graduated to engaging in hardcore performances, usually with younger men and women. She also founded the private photo and video studio called "The Kitten Klub." She famously appeared as a stripper at the bachelor party held by Sean Penn to celebrate his 1985 marriage to Madonna. In 2001, Natividad starred in the cult film comedy "The Double-D Avenger," directed by William Winckler, and in it, she was reunited with fellow Russ Meyer "repertory" stars actress Haji (from Meyer's "Faster Pussycat! Kill!") and Raven De La Croix from Meyer's film "Up!" In "The Double-D Avenger," Kitten Natividad played Chastity Knott, a woman who becomes a busty costumed crime fighter. In October 1999, Natividad underwent double-mastectomy surgery for treatment of breast cancer. After her breasts were removed, it was discovered that the silicone that had been used in her implants when she had undergone her 1969 surgery was of an industrial grade rather than a surgical grade. She subsequently underwent corrective surgery, and this brought her closer to the size that her fans remembered her having been. As of early August 2016, she was living alone with a pit bull and three cats, all of which were featured in the 2005 documentary movie "Pornstar Pets," and she continued to support herself with sales of her porn videos and phone sex. She appeared in the Adam Rifkin independent feature "A Night at the Golden Eagle;" according to her, Rifkin remembered recognizing her when their cars were both stopped at the same stoplight 25 years earlier. Kitten Natividad has appeared in more than 65 films and video productions. Career highlights and major studio features include:
