When a Penny meets an Antimemetic Penny, at least one completely ordinary cat appears in someone's home and they adopt it after posting lengthy twitter thread
They have never owned a cat before. They have never seen this(these) cat(s) before in their neighborhood. No one has because the cat(s) did not previously exist. They will like the cat(s) regardless of their opinion on cats. The cat(s) are otherwise unremarkable.

The intial thread will gain moderate traction and virality, but no further pictures or posts related to the cat(s) will exceed an audience beyond the individual's friends and mutuals.
The cat(s) are otherwise ordinary
