I'd read about this little phenomenon before I ever saw it. And I definitely didn't believe it until I saw it. But out of curiosity, how many or about what % of your T's do the happy dance after making a kill? Also, what species engage in this behavior? Only one of mine ever does it, and it happens to be my tubby little B vagans. He or she just loves to get on the tip toes and walk around in a rediculous fashion while bouncing up and down webbing the ground. Strangely enough it's the only one in my collection that isn't interested in dumping whatever dirt it can find into its water dish.
