Images of dogs seem more prevalent in baseball memorabilia (think D&M).
Here's an image of a cat on a 1940 Quebec ticket envelope, for Black Cat tobacco. There is also the written reference to Rock City, which had a number of baseball tobacco tins in the 1930s. For me, it's also neat that the writing refers to my birthday, just a few years earlier than my birth date 

Any other images of cats in vintage baseball?
