It gives it a more teddy bear feel that makes you want to peacefully snuggle with your bro.
Compare a cat in perfect shape that's a tsundere faggot or to his owners and murders innocent birds or squirrels for shits and giggles to a tub of fluff that lies around peacefully in the sun and feels enjoyable to hold.
