@*Girl Head sway is incredibly common with ruby-eyed/pink eyed rats as a way to improve their limited vision. It’s meant to improve depth perception by letting the brain see the same area from different angles to better judge distance, kind of like old fashioned stereoscopes/View Masters used two different photos placed in front of the eyes to give an image a 3D effect. You’ll probably notice more head swaying when the rat is readying for a jump, since distance is more important to get correctly when jumping vs running or climbing. Quite a beautiful girl! I had two sisters with similar coloring before, one was deep ruby eyed and the other had very light pink eyes, and they were just exquisite… Myshka & Matty, seen here enjoying some herbs in a dig box…
