Hi guys: Last night, while I was playing w/ my fuzzies, I noticed something really weird. They were jumping around & exploring everything & started whistling. They both STOPPED dead in their tracks, their eyes got really big & they started looking around the room to see what it was. So I stopped. And as they were about to go about their business again, I started again. They stopped again - they reminded me of little Stepford ferrets - whistle & they stop, stop whistling & they resume playing. Anybody have any ideas? Do you think maybe it hurts their ears - or is it just a quirk w/ my guys? Thanks, Jeanette Phillips [Posted in FML issue 1655]
