Hi Christa, 2 of my fuzzies do that, Taz and Hopper. It's whenever they're playing rough, that mine do it or when one of the cats is putting it's paws under the door trying to grab at them. It made me giggle the first time I saw it. It's odd but my girl, Abby, doesn't do it. I wonder if it's a mostly male thing or if it's just personality based? Angie :) [Posted in FML issue 4138]
