Country song... or perhaps it is the blues like the comments say

My kitty done left me (twang, twang)
when she saw a spot in the sun
My kitty done left me (twang, twang)
No backward look, just up and gone

Oh, kitteh... how I miss you now
Oh, kitteh... we lost it all somehow
I know that sun was shinin' bright
but whoooo kept ya warm last night
Oh, kitteh, somehow this don't seem right

(guitar interlude)

Well a good half hour done gone by
And time won't stop its steady slide, oh nooooo
You're snoozin in the shade again
and I ain't on the couch no more!
took the blanket with me too,
when you were gone and I was blue, goodbyeeeeee

My kitty done left me (twang, twang)
when she saw a spot in the sun
Oh, kitteh... (twang, twang)
I guess what's done is done
