Reruns of the show were not seen until the program began airing as part of the Boomerang programming block on Cartoon Network, which later became a spin-off network of its own.

For several months, Boomerang UK channel ran the musical interludes from the show, all of which ran to exactly 1 minute 45 seconds, as short (and unidentified) fillers before closing down at midnight.

When the channel expanded to 24 hours, these interludes were dropped.

Mildew Wolf, the most popular character on the program, resurfaced six years after the cancellation of Cattanooga Cats as co-host (with Snagglepuss) on Laff-A-Lympics, this time voiced by John Stephenson impersonating Paul Lynde.

Sky One occasionally broadcast Cattanooga Cats shorts in the UK in 1990, the segments were shown in complete isolation, broadcast neither as part of the original show or a new compilation.
