Every so often when I scritch Blu he almost flips over onto his back. He's getting closer and closer to going all the way upside down. I think it's adorable but I'm not sure what it means, exactly? Is he just being silly and playing? Is he getting sexually stimulated? Or do the stitches just feel so good that he goes all into it? I try to encourage it cause I love it and hope to hold him on his back one day, but don't want to do it if it gives him the wrong idea. I know macaws and conures roll on their backs but not sure if Quakers are known to?
