While the specific actors who played Morris haven't been widely documented, the commercials were extremely popular and became iconic for their catchy jingle and the character's mischievous personality.
The last commercial featuring Morris aired in 2009. Since then, the brand has shifted its marketing strategy and no longer uses the character. So, while Morris the Cat may not be around in new commercials, he remains a nostalgic figure for many people who grew up watching him on television.
