The 'Cat At Doorbell' meme, often featuring a cat captured by a smart doorbell camera like Ring or Nest, became a viral sensation for its strangely human-like behavior and fish-eye lens distortion. These images typically depict a cat standing on its hind legs or staring intensely into the lens, looking either like a polite solicitor or an ominous intruder. The meme gained traction on social media platforms like Twitter and Reddit as users shared actual footage of neighborhood strays or their own pets checking in. It is widely used to represent social anxiety when someone rings the bell unexpectedly, or to parody door-to-door salespeople and unexpected guests who won't leave.
