Miss Meow and I are playing with her milk ring. I throw it and she fetches it :)

I was not sure what you were referring to, so I looked up "milk ring." Oh my. Apparently people have their breast milk preserved in some sort of "stone" which is then fit to a ring they wear on their finger.

Dufuq?

Then I scrolled further and found a photo of the plastic ring on gallon milk jugs. Now I know what you mean.
