This kitty is the world’s fattest cat. At least that’s what the title of the video says. The cat weighs forty pounds, and moves like a walrus when it climbs the stairs! I feel like I need an adult diaper just to watch this video cause I just peed myself a little from laughing. No seriously. I think I may have to excuse myself for a moment. Remember kids… growning up isn’t all it’s cracked up to be.
