My cat (may she rest in kitty peace) Tweety, pictured below, kept trying to catch a fly who played dead--I kid you not! No sooner did she pounce on the "dead" fly did it take off and buzz around her, taunting and teasing her. It was a riot! Too bad I didn't have a camcorder (this was 1999) to get a video. Still, the memory was priceless!
