Slowed down animal sounds became a staple of pet meme editing because lowering the speed also lowers the pitch, turning ordinary meows and barks into human sounding chuckles and groans. This cat laugh version circulated on short form video apps and soundboards, where creators reuse the same stretched wheeze as a ready made punchline. It needs no context or caption to work, which helped it travel between platforms and languages. Editors still reach for it when a normal cat sound feels too quick and they want a longer, more exaggerated laugh to carry a scene.
