Compared are the shortened version of "The Cat That Laid the Golden Hairball" on the US DVD by Paramount and the uncut version on the German DVD by Turbine Classics.

The differences:

1 cut = 42 seconds

The Ren & Stimpy Show is one of the most over the edge cartoon shows ever. So it's no surprise that Nickelodeon US - similar to Disney - reacted to the feedback of the audience and made a few cuts. On top of that, later broadcasts on Spike TV contained further alterations. More cuts were made and, if required, some scenes had a higher frames per second rate in order to reach the regular length for syndication. These versions are the available ones on the so-called "uncut" US DVDs by Paramount.

Surprisingly enough, the German broadcasts back in the 90s were almost uncut, only a few scenes with too explicit footage were removed.

For the uncut box the comparisons have been made with, Turbine Germany used the cut (but restored) US masters and the original German versions in order to put the longest versions possible on the German DVD set. Missing scenes in the US Versions have been filled with the German version (including the German dub), missing scenes in the German versions have been filled with the US Version (and they got subtitled in German, if necessary). The result is the longest version available of every single episode.

The shot of the hairballs lying on the assembly line is longer. Then Stimpy is shown removing the hair on a really hairy belly with his tongue and spitting them on the assembly line again. A fat guy is standing at the end of the assembly line and puts the hairballs into the boxes behind him. The speed of the hairball production then increases and the fat guy runs out of breath. After that, we see Stimpy again, who still keeps spitting out hairballs.
