Cool Cat was a tiger (whose design was very similar to that of The Pink Panther and Snagglepuss) who wore a stylish green beret and scarf. Unlike most other Looney Tunes characters, Cool Cat was unapologetically a product of his time. He spoke in 1960s-style beatnik slang and acted much like a stereotypical laid-back 1960s teenager — he was often seen strumming a guitar or traveling cross-country in his dune buggy. One cartoon — McKimson's Bugged by a Bee — depicted him as an alumnus of "Disco Tech" playing varsity football against the long-haired team from "Hippie University"..
However, most of Cool Cat's cartoons dealt with his encounters with Colonel Rimfire (both voiced by Larry Storch), a fussy, British-accented big-game hunter armed with a shotgun. Rimfire essentially acted as the Elmer Fudd to Cool Cat's Bugs Bunny, but was used only by Lovy. Cool Cat bears the distinction of starring in the very last cartoon produced at the classic Warner Bros. Cartoons studio: Injun Trouble in 1969. Shortly after this cartoon was produced, the venerable animation studio shut down for good.
His cartoons can easily be distinguished from most of the other Looney Tunes cartoons, for they feature an updated Looney Tunes logo with stylized animation, a 1967 remix of "The Merry-Go-Round Broke Down" by William Lava, and featuring the then-current Warner Bros.-Seven Arts logo (a combination of a simple W and 7 inside a stylized shield outline).
