I remember a getting a book out from the school library in grades 4-6 (1967-1970), though it might have been an older book even then. Don’t remember much about it except it took place in the fall, I’m thinking around Thanksgiving? and it may have had a mix of humans and animal characters in it. The reason I say this is I distinctly remember on the last page that a little girl goes back to someone’s “ house” that may have been  in a tree stump? and had coffee and pumpkin pie. Definitely not “Cranberry Thanksgiving”, but had the same cosy, New England, kind of feel to it.
