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.
御庭摘希（大久保瑠美 配音）是一个有着紫色长发和呆毛的傲娇少女，个性呆萌又别扭的她有着一个心上人——音无伊御（冈本信彦 配音）。在伊御的眼中，摘希是一个需要照顾的小妹妹，这让摘希觉得十分抓狂。虽然完全没有自觉，但是伊御时常会做出一些让摘希无法承受的刺激举动。 围绕着这一对友达以上恋人未满的笨蛋情侣的，是一群有趣又善良的朋友们。天然呆的春野姬（福原香织 配音）总是被爱捉弄人的科学怪人片濑真宵（生天目仁美 配音）耍得团团转；而有着僵硬症的戌井榊（浅沼晋太郎 配音）又总是在笑料达到高潮的时刻浑身僵直不能动弹。这群可爱的朋友们，围绕着他们而展开的日常就是这部动画所要表达的主要内容。
