Top Cat was a Hanna-Barbera prime-time animated series which premiered in 1961 and ran for 30 episodes and which remains one of the studio's most enduring creations.

The central character, Top Cat (his friends call him TC) is the leader of a gang of Manhattan alley cats: Fancy Fancy, Spook, Benny, Brain, and Choo Choo.

There are distinct resemblances to the popular US situation comedy The Phil Silvers Show (on which the cartoon is said to have been loosely based) in the relationships between the characters. Arnold Stang's voicing of Top Cat strongly resembled Phil Silvers' voice as well.

A frequent plotline revolved around the local patrolman, Officer Dibble, and his ineffective attempts to evict the gang.

In the United Kingdom, the show was renamed Boss Cat (by means of a crudely substituted title card) when it was first aired on BBC1 because Top Cat was the name of a brand of cat food.

Of course, the dialogue still referred to the character by his original name. By the 1980s the original title was used in reruns and this continues on the Cartoon Network UK.
