1x19 - Tom and Jerry: The Chuck Jones Collection

When Tom falls in love with another female cat and offers her Jerry as a gift, Jerry screams and then tells her about the incident. Turns out that Tom planned it out, and she feels sympathetic for Jerry, and decides to take care of him. Jerry keeps trying to get into Tom's mouth on purpose, which gets Tom into trouble with the female cat. She eventually kisses Jerry, but upon tasting him, she smacks her lips with a devilish look on her face, teams up with Tom, and chases Jerry, with the intention of eating him, until the end of the episode.
