Those ears try to flick and move as they are chewed on. It's a strange feeling and those also have a mind of their own, reacting more to Wei Wuxian's emotions then him having any actual control over them. Luckily most of his body hasn't changed, just the sharper nails that Wei wuxian has tried very hard to make sure he doesn't scratch anything or anyone with.

He enjoys the feeling of those hands though as they wander and pet along him.
