Lil Bub was a world-famous celebrity cat known for her unique appearance caused by several genetic anomalies, including a shorter lower jaw and a rare bone condition, which resulted in her tongue always hanging out. Discovered as the runt of a feral litter in 2011, she quickly became an internet sensation, representing resilience and spreading a message of positivity. Her owner, Mike Bridavsky, often claimed she was a 'magical space cat' from another planet. In the meme world, Lil Bub is used to convey pure joy, 'derp' moments, and wholesome energy, making her one of the most beloved animal icons in digital history while raising significant funds for animal charities.
