I doubt it is cancelled, LatAm Comedy Central is airing reruns of Ren & Stimpy and they are doing well, they even upload clips of the show to their youtube channel regularly to what I assume is promote the upcomign reboot and they get lost of likes and positive comments: https://youtu.be/1vT9NPGlYsQ
People outside USA doesn't give a shit about this "drama", Also Comedy Central cancelled most live action shows because they wnated to focus on adult animation if they cancel Ren & Stimpy they would be left with only 3 cartoons instead of 4: >The Clone High reboot. >The Beavis and Butt.Head reboot. >And the Daria Spin off.
Not a smart thign to do after you cancelled most live action stuff to go for animation instead.
