German version was released to cinemas with a "Not under 12" rating. A few days after its release the film was edited by the distributor to remove some violence (for a younger and larger audience) and was re-submitted to the German ratings board (FSK) which gave the cut version a "Not under 6" rating. This version was also used for the DVD & video release. The uncut version is currently not available in Germany.
The DVD extras feature the original, alternate ending where Sophie instead takes Mr. Tinkles to a pet hospital to be neutered, but the cats intercept her and Tinkles makes his escape.
