"If It Fits, I Sits" is one of the internet's most enduring lolcat catchphrases, epitomizing the bizarre feline instinct to occupy any container, regardless of its size. The phrase gained massive popularity on platforms like Reddit and Tumblr in the early 2010s, often paired with photos of cats overflowing from tiny cardboard boxes, sinks, or even glass bowls. It highlights the humorous logic of cats who believe that if they can physically wedge themselves into a space, they belong there. Today, the meme has evolved beyond pets to describe any situation where someone or something is stubbornly crammed into an ill-fitting spot, serving as a global staple of wholesome internet humor.
