I find the whole situation hilarious and on topic for this forum, so I'll just write what I know.
2 days ago someone created that sub with a description "a sub for pics and videos of cats fucking". Then they were legitimately surprised to find out that in like 3 hours someone actually posted cat porn (just cats). 2 hours after creation there was already a post on /r/AgainstdegenerateSubs and now they have a voting whether or not to ban cat porn because of reports. The photos got removed. The results are pretty even: 23 for banning, 20 for not.
