Even played very softly, an Olwell F bamboo flute can – and will – plunge barnyard roosters into a veritable Greek chorus of crowing at 2:30 a.m. 
Mubu the Cat, who seems to love Irish music and finally now approves of my flute playing, has a particular fondness for the album “Kitty Lie Over” by Mick O’Brien and Caoimhin O Raghallaigh (sp?). I think that those flat sets in B and Bb along with the tuned-down fiddle might be close to feline vocal ranges, hence her affectionate snugglings when I play it. Maybe it’s just good taste on her part.
My parrot,Jr.,dances to jigs and hornpipes.She bobs up and down,and side-steps left and right.My family all think it’s hillarious,and always whistle a tune to her when they come in my room.
One of my friend’s greyhounds likes to “sing” along whenever she plays.
It’s really starting to p#ss her off, since it’s impossible to practice while her hounds are all singing. (If one starts, the others will jump in.)
Not the reason I quit playing Saxophone, but not an encouraging factor:
I was living on our family’s cattle ranch, and every time I practiced the cattle would line the fence nearest our house and join in. Have you ever heard a couple of dozen cattle attempting to harmonize? 
Omigosh, that’s what my neighbor’s cows were doing the other day! And then there are the dogs. One goes and hides, and the other lies on my feet with a look of utter forbearance. The cat disappears unless I get out the whistle, and then wanders the house yowling.
It’s a really, really good thing I live in the country.
