|Jeff and I just discovered that Giggidy (meemer) goes nuts when she hears an Indian flute. I was playing the viddy from an old post and she went bersker, looking under my laptop for the source of the sound.
I thought maybe the high frequencies make her think of kittens, but Jeff did a little research and found that other female cats had a similar reaction. They do this twitchy meow, which secretes a chemical from their glands that enhances smell. They think the sound is a bird singing.
