^ I agree with Soul, it makes sense to have realistic animal signals, like the tail fluff and back fur on end. It'd be cool if there were other body gestures too, both canine and feline, that had sounds... and maybe emotes that automatically pop up with it too... like a fixed face emote, tail emote, and body emote all put together in one action.
Example: If a theme is angry, then...
-You press 'C' for one action, or shift 'C' for scrolling through different actions, like the 'Z' button for sleeping and laying down.
-Once you scroll to the 'angry' action on a feline, your tail emote would be the one on the picture, the body emote would be the fur standing on end and back scrunched up, and the face emote could be rage.
-Sound could be a low growl/hiss.
