The Kitten growth video has viewers doing a double-take after a tiny fluffball turns into a full-size chonk. It starts with a baby Siberian cat perched on a scratcher, looking too small to cause trouble. Then the clip jumps ahead, and suddenly he fills up the couch like he pays rent. The before-and-after moment feels extra funny because the reel leans into the surprise with captions and a dramatic pause.
Kitten is now a ‘whole chonk of a cat’ in adorable video
The viral reel was posted by @hercozycrew, a cozy home and pet content creator based in Ontario, Canada. In the caption, Carly T says she brought home a 1.5-pound kitten at the start of May 2025. By January this year, he reportedly weighed 11 pounds and looked like a “whole CHONK OF A CAT.” The post uses original audio and shares a quick timeline of his sudden growth.
The video opens with the smallest version of him, sitting upright and staring at the camera. On-screen text reads, “He’s so cute and tiny I don’t think he’ll get that big!” His fur looks extra plush, and his little face seems curious and innocent. Then the screen flips to “7 months later:” and the mood changes instantly. He now lounges on the couch with confidence, legs out, like a grumpy king.
Carly T also adds that his first birthday is not until February 14. She notes Siberian cats can mature slowly and may reach full size around age three. That detail makes the glow-up even funnier, since he might get bigger, and some commentators also call him “Valentine baby”. The kitten growth video also sneaks in a playful line asking if she brought home “a kitten or a dog.”
Reactions were loud and entertaining. One commenter wrote, “why is he sitting like that.” Another said, “he’s so fluffy!!” A third added, “what a distinguished little gentleman.” Others joked, “He’s adorable at both ages?❤️” and “The classic Siberian transformation ? He will get bigger in few more years❤️.”
