Song From Grandmother

I remember Grandmother singing this song to me when I was a child.

Six little mice sat down to spin,
Kitty passed by and she peeked in.
"What are you doing my little men?"
Making good coats for gentlemen.

"May I come in and bite off your thread?"
OH NO! Miss Kitty, you will bite off our heads!
"Oh no I won't I'll help you spin."
That may be so....But you CAN'T COME IN! Author unknown
