Mine? Mine would probably be my tendency to smell a lot of things, and I also sneak up behind my peers, it tends to surprise them (I walk more on my toes). I also have a tendency to wear fur hats all the time (I come from a very cold climate, but I tend to wear it in the summer, when it gets to around 30 degrees Celsius). I also scratch behind my ear, and I get very edgy when someone's hand goes near the front of my body (i.e. chest, abdomen, &c.).
Other things, not necessarily bad, I like my back/head scratched, I skip stairs/climb on all fours almost all the time, and tilt my head when I don't know the answer to a question. I also sit cross-legged. I recognize people by the way they smell, I have a great sense of smell. I also have terrible social anxiety.
After reading the stuff on this thread a lot of stuff I do could be considered furry stuff!
