My cow collection started with receiving a white cow creamer from my husband on our first Christmas together 31 years ago this Christmas. (I now have several cow creamers -- all slightly different.) When the kids were little, I poured milk into the original cow creamer & then I poured the milk from the creamer into their cereal bowls. I know, kind of complicated, but I was trying to be supermom. (Never got it right, by the way.)
I also have a cow cookie jar with a yellow chick on it's back.
I really should make a cow quilt, huh?
