my dog comes in to my room and sings - at least I think he does. I’m sure he’s not whining (he could be when I play pipes tho) because when I play my fiddle he sings too - and I’m prety good on the fiddle… also as back up proof: a friend of mines dad plays the fiddle and he sings to him too so i dunno…
I did have a pair of cats that would actively get up in my lap when I whistled… and get very loving… but I finally figured out that they were really just trying to dislodge the whistle so I would cease the infernal racket.
my two cats hate highland pipes, will tolerate uilleann pipes if they don’t want to leave their spot, and seem pretty apathetic towards whistles; my black tabby loves the banjo and my orange tabby is partial to the piano
