Need some input...
Chance has been crankier in recent weeks, stubbornly not stepping up, and biting my spouse after asking to step up, trolling him. She won't step up for me, but she does for my spouse, then biting him. She seems to be more willing to bite him than me. Still, she won't step up for even me. She does this hang-upside-down thing in her unwillingness to step up when I offer my arm. Even if I repeatedly tell her to step up, she won't until she decides if she wants to cave in.
Once on, she'll crawl to the shoulders and lightly nips/beaks the sides of the face and hair around the face while on the shoulder.
Any guesses as to why Chance has been so moody recently? This behavior has come with the winter months. Not sure if it has anything to do with the Winter season. She is just being less affectionate, over all. She will still cuddle, but rarely, and it's on her terms. The not stepping up at all is a first. It's like she is just less social.
