A "Cats" postage stamp was issued by the United States Postal Service in 2000 as part of its Celebrate the Century series. The musical was chosen as one of fifteen "outstanding artifacts, events and activities" from the 1980s to be commemorated with its own stamp design. Beginning in March 2019, the Rinkai Line in Tokyo, Japan, uses two songs from the musical for its train departure melodies at the Ōimachi Station; the train to Ōsaki Station uses a jingle of "Memory", while the train to Shin-Kiba Station uses a jingle of "Skimbleshanks: The Railway Cat".
