A friend of mine has a tortie cat who has her buttons pushed by harmonica. My friend has a bit of a tin ear so she can't play but when she blows (whee-hoo, whee-hoo) on the harmonica, the cat gets as close to her mouth as possible, kneading my friend's chest, eyes closed in perfect bliss... It's something to see. Is there an explanation for this kind of thing?
