Cats get very offended at higher end of whistly things, one tries to sit on my head & knock it out of my mouth. Dog (aged yellow labrador) is rather deaf so doesn't mind at all, another dog we had would sing beautifully to clarinet accompaniment (howl??). The geese love flute music, waddle over and sit at my feet with their heads on one side staring with one beady eye. The goat remains indifferent...
