Wow! Although they look nothing alike, my Maggie and your Grace have a lot in common. Maggie is a tabby, looking something like Kitty. She's 12 years old and WAY too fat (my fault for giving her too many treats), but as a kitten she fetched crumpled up cigarette packs OR those red milk rings you spoke of. And, I mean, she'd do it for an HOUR at a time - tear-assing all over the place to retrieve those things. Plus, she slept on her back all sprawled out. I don't have any good pictures of Maggie because she hates pictures and won't sit still long enough for me to get a good one.
