In honor to celebrate the 15th anniversary of Garfield, CBS aired the sixth season in 1993. For this season, the titles changed at the beginning. Instead of showing clips from only the first two seasons, which is what happened for the last three seasons, the titles included more clips from the fifth season, plus some from this season and one from a second season episode Health Feud, but still retaining a large amount of the original clips. However, the theme tune remained the same. Episodes 90–96 are available on the Garfield and Friends Volume 4 DVD set. Episodes 97–105 are available on Garfield and Friends Volume 5 DVD set.

懒惰却又聪明的肥猫、又笨又可爱的傻狗和一个整天迷迷糊糊的主人乔恩之间的搞笑日常故事。

In this season, the show went back to airing one new episode a week, but stayed in the hour-length format, filling up the second half-hour with episodes from previous seasons and some of the prime-time specials from the 1980s. This entire season, along with the second half of season 6, is available on Garfield and Friends Volume 5 DVD set. Also worth noting is that here, a new theme song was added that was written by J.R. Johnston and Neil Panton. The theme was sung by J.R. Johnston. This theme song was not shown internationally, and as a result, it does not appear on the DVDs (although Garfield's quotations are kept intact). This new introduction sequence used most clips from Seasons 5-7 and a few from the first two seasons, as well as Garfield in Paradise and Garfield's Feline Fantasies. The episodes stopped using a few seconds of the theme playing in the episode title cards after season seven's fourth episode; music from the episodes were used in the title cards until the show ended, even though season six used music from some of their episodes.
