I've always mentioned Aly's ears and tail as if she were a cat, having done some of the same research as you. I know that her tail fluffs up if she's scared, her ears fold back and tail lashes if she's angry. Her fangs sometimes hang on her lip if she's feeling cheeky. I've never left her tongue sticking out like my cat does though...although I'm sure that that would lead to an interesting conversation with fellow characters.
I know RPers who really work well with the other senses. Tessa Jalloh, for instance, is very good at incorporating scent into RP. Tessa keeps tabs on everyone's scent, asking fellow RPers what they think their character would smell like, and then keeps mental notes of that in case she encounters someone or whatnot. I've always looked at people who are able to do that in RP and be awed by it. It's such a cool quirk to have, and to be able to do it well is admirable.
