Ren and Stimpy were not openly recognized as a canon same-sex couple until the Ren & Stimpy Adult Cartoon. This new series targeting adult audiences aired on the new Spike TV. The press release at the time stated: “the duo is back -this time as a gay couple”
In retrospect, it is almost shocking that a children’s show like Ren and Stimpy was made at all, considering the Care Bear fare of the eighties. But the nineties gave creative freedom back to the animators.
