The Hep Cat opens with a cat strolling through an abandoned lot. Unfortunately, he stumbles across a dog named
Rosebud, who gives chase. The cat, after a successful escape, begins singing a parody of "
Java Jive". Later, the cat encounters an attractive female cat, and attempts to woo her, failing utterly. A package containing flowers and a lipstick-kissed note is tossed over the fence; the note invites the cat to rendezvous with "guess who?" on the other side of the fence. He prances over and comes face-to-face with Rosebud. The chase resumes. At one point, the dog uses a puppet version of the female cat of Hep Cat's dreams to trap him. The cat is fooled and again the dog pursues him. After a series of zany sight gags, the cat once again evades Rosebud and puts him out of commission. As the cartoon closes, the cat can be seen kissing his dream girl—the
puppet. ==Voice cast==
