I saw this shared and it was weird enough to trigger my possible BS detector.

I am happy to report this is indeed true. She even appeared on Jimmy Fallon to confirm it (video not available but the summary is)

@ellesaurus @dannotdaniel Yesterday I learned of a theory that Taylor Swift is secretly on 4chan. One evidence is that a channer asked for advice on naming a cat, with a picture, and someone suggested Merideth. The very next day, Tay announced her new cat's name, Merideth, with a different picture of what looked to be the SAME CAT.

idk but it's interesting to think about.
