Yes, that's pretty much how Charlie reacts to Yertle, my turtle. In fact, on the day I introduced them, Charlie was more freaked out than Yertle was! He still has to watch when Yertle eats and when he walks around (he's not in a cage), but he never tried to hurt him. He even tried to play with Yertle once-he "kicked" his little ball of yarn to Yertle and kept waiting for Yertle to kick it back. It was the funniest thing! Yertle just sat there like, "what am I supposed to do now??" My little sweethearts crack me up!
