Heathcliff is an American comic strip created by George Gately in 1973,[2] featuring the title character, an orange cat.

A regular feature in the Sunday strips is Kitty Korner, where unusual cats in the real world are described.

Readers often interpret it as surreal humor without logic, though Peter Gallagher claimed in an interview with SOLRAD that "I'm not just doing stuff that doesn't make any sense at all".

Star Comics added an additional spin-off title in 1987 called Heathcliff's Funhouse (which also switched over to Marvel with issue #6).

[8] Two animated TV series based on the strip, both simply named Heathcliff, were created.

Although Heathcliff does not speak in the comic strip, both animated versions of the character were voiced by Mel Blanc.

The first season featured segments with Dingbat and the Creeps (Dingbat is the vampire dog (Frank Welker) accompanied by Spare Rib the skeleton and Nobody the jack-o-lantern who were both voiced by Don Messick), which were created by Ruby-Spears for the show, and the second season featured fellow comic strip character Marmaduke (voiced by Paul Winchell).

[11] As of 2021, Legendary Entertainment has plans to simultaneously develop a TV series and film based on the Heathcliff comics.
