Eyebrow Cat, specifically featuring a white feline named Gary from the UK, became an internet sensation due to the unique black markings above his eyes that resemble permanently raised eyebrows. First gaining major traction on Instagram and news outlets around 2015, Gary's perpetually concerned expression makes him the perfect template for situations involving shock, confusion, or existential dread. Unlike many other cat memes that rely on action, Eyebrow Cat succeeds through pure facial expression, capturing the exact moment someone hears a piece of news they weren't quite ready for or realizes they've made a terrible mistake.
