Looking for the title of a 1960's movie where a family travels in a station wagon to a cabin(?) that is ramshackle and they find a family of raccoons in the oven or kitchen cabinet, I think it's black and white

Snowball Express (http://www.imdb.com/title/tt0069291/)?

Thanks! I thought that too but the question is my sisters and she says the synopsis doesn't sound right... she remembers it in b&w and not in winter
