UPDATE: I got a tweet today from someone claiming to be Imgur user, and creator of this cat video, Celestialstein, and she is pissed.

Wow, it was super sexist to assume the person who filmed this video was a man. It really only came up in the title, but I can see how it might be upsetting to be misgendered in a viral cat post. It's like that "riddle" about the doctor, where the doctor's son and husband are injured and the doctor can't operate, because it's too upsetting. And you're like, how can a doctor have an injured husband?? Because that would either mean they were a gay couple...or the doctor was a woman the whole time!!!!! OW, MY SEXIST BRAIN!
