Now we already KNEW that Telemna is good at sounds: http://www.youtube.com/watch?v=ayJ-WvVaRnE and there was an annoying whistle in the basement for the last two days, but the sound was reflecting a lot so the source could not be found. (In fact, the condo handyman who checked the new smoke alarm to make sure that its capacitor was functioning offered to drill some holes in the basement ceiling to try to locate it, and I even wound up with my ear to our wonderful downstair neighbor's door while he was away to see if it was from there (in which case I know who has his spare key so she and i would have tended to it as we did during a problem in the past year). None of us could find the source. Then Steve figured that Telemna has the best ears in the family and he took her downstairs. She did NOT want to be near that sound and tried to get away so he walked through the room with her asking, "Where is it?" Our ferrets are pretty used to the word "where" and after a little bit she understood what he was asking and pointed him to one of our pieces of exercise equipment, a stepper we've been using for about 15 years. That was it. The battery was failing but so was the low battery alert sound, so it instead created a horrid constant, high pitched whistle. When Steve pulled out the battery and it stopped Telemna rewarded him with many huge kisses. Then he brought her back upstairs for a treat.
